- [Heat transfer coefficients in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/heat-transfer-coefficients-in-star-ccm/): Convectional cooling is generally governed by Newton’s law of cooling, which states that the rate of heat loss of a body (q”) is proportional to the temperature difference between the body (Tsurf) and its surroundings (Tref). The proportionality factor is known as the heat transfer coefficient (HTC) and usually denoted h: If the component is colder than its ambient, the temperature difference will be negative, but so will the heat flux, hence the HTC is always positive. When setting up a conjugated heat transfer simulation in Simcenter STAR-CCM+ you will quickly notice that there are multiple HTC field functions that might look […]
- [New pre-processing features in Simcenter STAR-CCM+ 2606](https://volupe.com/simcenter-star-ccm/new-pre-processing-features-in-simcenter-star-ccm-2606/): Simcenter STAR-CCM+ version 2606 was released on 1st of July, and this version was packed with great new features for CAD and meshing. In this week’s blog post we are therefore taking a closer look at the highlights for pre-processing.

- [Knowing when a Pareto front has stopped moving](https://volupe.com/simcenter-heeds/knowing-when-a-pareto-front-has-stopped-moving/): The problem with multi-objective optimization   Anyone who has run a multi-objective design study knows the concern of not knowing when to stop. In a single-objective optimization study, convergence is easy to reason about: there’s one performance score, and you can watch the best-so-far value flatten out. Multi-objective Pareto studies aren’t so easy. Instead of chasing a single best solution, we are searching for trade-offs between conflicting objectives that are “equally good”, means none of which dominates the others across all objectives. Consequently, we must track the performance of multiple solutions and come up with a procedure to quantify the convergence. […]
- [Time-step selection in a conjugate heat transfer analysis](https://volupe.com/simcenter-star-ccm/time-step-selection-in-a-conjugate-heat-transfer-analysis/): Selecting a time-step size in a transient simulation is a matter of assessing how fast you can progress the solution while still being time-accurate. In other words, how fast can you progress while still capturing all relevant physical phenomena. In many transient CFD analyses, the solution progression is typically limited by the transient evolution of fluid flow. But in a conjugate heat transfer analysis, there may be cases where the thermal transient within a solid evolves faster than the flow field, particularly when highly conductive materials such as aluminum or copper are involved. In this article, we will describe what measures […]
- [Simcenter STAR-CCM+ 2606 Multiphase news](https://volupe.com/simcenter-star-ccm/simcenter-star-ccm-2606-multiphase-news/): It is time again to look at the latest version of Simcenter STAR-CCM+ 2606 and what it brings for the different multiphase simulations. The latest version of Simcenter STAR-CCM+ was released in the beginning of July, meaning it is high time to learn what we can do with it. Phase change using Phasic Porous media with EMP During my seven years working as an application specialist, I have been asked several times if it is possible in Simcenter STAR-CCM+ to simulate heat pipes. The answer to that question has always been that the size scale of that problem lies outside the […]

- [How to set up acoustic simulations in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/how-to-set-up-acoustic-simulations-in-simcenter-star-ccm/): Welcome back to our acoustic simulation series. In this week’s blog post we provide guidance for how to set up your simulations in Simcenter STAR-CCM+, and which settings should be used in the GUI. As mentioned in the previous blog post about acoustics, https://volupe.com/simcenter-star-ccm/capabilities-for-acoustic-simulations-in-simcenter-star-ccm/, the strategy to resolve and obtain accurate results for pressure fluctuations is by first running a RANS simulation and then refine the mesh in order to run a LES simulation. For the RANS compatible acoustic models it is sufficient with a RANS resolution, but generally you will need LES for accurate acoustic simulations. In this blog post […]
- [PhysicsAI Add-on for Simcenter-STAR-CCM+](https://volupe.com/simcenter-star-ccm/physicsai-add-on-for-simcenter-star-ccm/): In version 2602 of Simcenter STAR-CCM+, the highly anticipated tool Simcenter PhysicsAI was introduced into Design Manager as an Add-on. With this new Reduced Order Modelling (ROM) approach, CFD engineers are now able to configure AI models based on either historical results, obtained during say a previous design cycle, or set up a completely new Design Manager study with the purpose of training a much faster data-driven mathematical model.   There are several reasons why this workflow can benefit your simulation work, but in essence, this new type of geometrical ROM enables rapid exploration of design variations in a flexible and […]

- [Make Better Use of Your Time with Time Step Control in Simcenter Nastran](https://volupe.com/simcenter-3d/make-better-use-of-your-time-with-time-step-control-in-simcenter-nastran/): When using Simcenter Nastran to simulate nonlinear structural phenomena it can be a bit of a jungle to wrap your head around the time step settings. These involve the number of step increments and their impact on output written to the database as well as how they interplay with adaptive time step settings. In this blogpost we look closer at these specific settings regarding time step control.
- [DFBI Mesh Morphing for Ship Maneuvering Simulations](https://volupe.com/simcenter-star-ccm/dfbi-mesh-morphing-for-ship-maneuvering-simulations/): Marine maneuvering simulations in STAR-CCM+ can be approached in two fundamentally different ways. The Moving Forced Wave Tank (MFWT) with overset mesh is the go-to for complex wave environments and large excursions. But for moderate-motion cases, especially calm-water or mild-wave maneuvering, DFBI mesh morphing in a single domain offers a cleaner, overset-free alternative. This post walks through the complete morphing setup, including how to superpose a time-varying rudder rotation on top of the ship’s six-degree-of-freedom motion. Two approaches to maneuvering simulation The Moving Forced Wave Tank approach The conventional setup for ship maneuvering in STAR-CCM+ pairs DFBI Rotation and Translation motion […]
- [Capabilities for acoustic simulations in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/capabilities-for-acoustic-simulations-in-simcenter-star-ccm/): In this week’s blog post we are looking into acoustic capabilities and models in Simcenter STAR-CCM+. Since there are several models for acoustic applications it is important to understand their differences and when to choose which model. We will describe the models by starting with the least computational expensive one and then go to more accurate models, but first we start with some general information and theory. General guideline  Sound propagation originates from small pressure fluctuations within the fluid. To resolve these pressure fluctuations, it typically required to have both fine mesh resolution and a small time steps. The frequency range that humans can hear is from 20Hz to 20kHz. The highest level of accuracy (Direct noise calculations) does therefore (at least) require LES resolution of the mesh, to resolve all frequencies of pressure fluctuations. There are several models to help you obtain results even though you cannot afford […]
- [Tangential plotting along a circular line in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/tangential-plotting-along-a-circular-line-in-simcenter-star-ccm/): Plotting along a line can be done easily in Simcenter STAR-CCM+ using a Line Section or Line Probe derived part, but these derived parts are limited to straight lines. Imagine instead that you want to plot field data along a curved line, e.g. as a function of angular position. For this scenario there is no native derived part to be used, so you need to be a bit creative to achieve this. In this blog post we will demonstrate how to get it done. Demonstration case To demonstrate the workflow we will use a dummy case where we induce a recirculation […]
- [Simcenter Flomaster – Options for Pipe Heat Transfer](https://volupe.com/simcenter-flomaster/simcenter-flomaster-options-for-pipe-heat-transfer/): Predicting heat transfer behavior is a fundamental aspect of thermo‑fluid system design.

We highlight how different modeling approaches and configuration options influence thermal behavior, simulation fidelity, and the quality of engineering decisions that can be drawn from the results. Furthermore, the additional information may lead to more accurate simulation results […]
- [Studio Scenes in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/studio-scenes-in-simcenter-star-ccm/): There is a new sheriff in town! Studio scenes! At least when it comes to photorealistic rendering in Simcenter STAR-CCM+. I have earlier posted about advanced rendering in our blog, and here are the links to those posts: Advanced Rendering In Simcenter Star-CCM+ – Volupe.com, Advanced Rendering In Simcenter STAR-CCM+ Part2 – Volupe.com. The advanced rendering is still possible to use in Simcenter STAR-CCM+, but the studio scenes proved a lot more speed when it comes to rendering. The studio scenes were introduced in version 2506, almost a year ago. The reason why studio scenes are potentially faster is the fact […]
- [Optimization Intelligence](https://volupe.com/simcenter-heeds/optimization-intelligence/): One of the most common questions asked, working with design optimization is deceptively simple: “How many evaluations do I actually need?” It sounds like it should have a clean answer. It doesn’t and that’s not a flaw, it’s a reflection of the genuine complexity involved. HEEDS 2510 addresses this head-on with a new Optimization Intelligence feature that brings intelligent, automated guidance directly into the setup workflow. Why the question is so hard to answer The required number of evaluations depends on a web of interacting factors: the algorithm selected, the number and type of design variables, their ranges, the nature of […]
- [Improved motion capabilities for Smoothed Particle Hydrodynamics (SPH) in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/improved-motion-capabilities-for-smoothed-particle-hydrodynamics-sph-in-simcenter-star-ccm/): The 2025 year’s releases of Simcenter STAR-CCM+ included some substantial improvements for the Smoothed Particle Hydrodynamics (SPH) solver, and one of the most exciting ones may be the compatibility with the Dynamic Fluid-Body Interaction (DFBI) motion. With this addition the application coverage for SPH is hugely increased, as you can now model kinematics and multi body motions, as well as fluid force induced motion. How to use it The functionality is enabled through the new motion called DFBI Meshfree which was first introduced in the 2506 release. As with all other motions, the DFBI Meshfree motion can be found under Tools […]
- [Simulation-Driven Automation with Simcenter Systems](https://volupe.com/simcenter-amesim/simulation-driven-automation-with-simcenter-systems/): Industrial machinery is typically controlled by programmable logic controllers (PLCs), making it essential to verify control software before connecting it to real equipment. By testing PLC logic and system behavior on a digital model using system simulation, engineers can identify issues such as design flaws, inadequate component sizing/selection, faulty control logic, or inefficient control strategies early in the development process. Virtual testing in this manner reduces late‑stage changes and reduces the cost of expensive on-site debugging during startup and project build. Tight collaboration between hardware engineering and control‑system teams is essential in any development. This approach not only compresses the overall […]
- [Leverage Assembly FEMs in Simcenter 3D to Simplify Modelling](https://volupe.com/simcenter-3d/leverage-assembly-fems-in-simcenter-3d-to-simplify-modelling/): In today’s Volupe blog post we will have a look at the assembly FEM functionality in Simcenter 3D, which is great when larger assemblies containing multiple bodies are to be modelled.

Logos are one of these features that are often unnecessary to resolve and therefore removed manually. […]
- [GPU-accelerated calm water resistance in Simcenter STAR-CCM+ 2602](https://volupe.com/simcenter-star-ccm/gpu-accelerated-calm-water-resistance-in-simcenter-star-ccm-2602/): In Simcenter STAR-CCM+ 2602, Siemens has expanded general-purpose GPU coverage so that a larger part of the solver stack can execute on the GPU. Please refer to previous blog article for an detailed walk through of the latest implementations. The idea behind general-purpose computing on graphics processing units (GPGPU computation) is that you assign computations that are traditionally solved on a CPU. Most, but only certain solvers in Simcenter STAR-CCM+ are compatible with running on GPGPUs. If you select a solver that is not GPGPU-compatible, the entire simulation runs on the CPU instead. That changes the practical question from “Can I […]
- [GPGPU Enhancements in Simcenter STAR CCM+ 2602](https://volupe.com/simcenter-star-ccm/gpgpu-enhancements-in-simcenter-star-ccm-2602/): The release of Simcenter STAR‑CCM+ 2602 delivers some significant steps forward within GPU ‑accelerated CFD.

- [Simcenter STAR-CCM+ 2602 Multiphase news](https://volupe.com/simcenter-star-ccm/simcenter-star-ccm-2602-multiphase-news/): It is time again, a new version of Simcenter STAR-CCM+, this time version 2602. This release will be at the end of this month, so this post is a teaser as it is posted. With every new version, there is also a post about the multiphase news associated with that version. This time around, the Eulerian and Lagrangian Improvements and new models, are fewer, so there will be some more emphasis on the SPH (Smoothed Hydrogen Particles) news. But let’s dig into what we got. Energy compatibility with Phasic Porous media and EMP The phasic porous media was introduced last year, […]
- [Simcenter Physics AI workflow, based on a Simcenter STAR-CCM+ study](https://volupe.com/simcenter-star-ccm/simcenter-physics-ai-workflow-based-on-a-simcenter-star-ccm-study/): Simcenter Physics AI is an Altair software, now included in the Simcenter Portfolio, based on Geometric Deep Learning (GDL).

- [New features for CAD and mesh in Simcenter STAR-CCM+ 2510](https://volupe.com/simcenter-star-ccm/new-features-for-cad-and-mesh-in-simcenter-star-ccm-2510/): This week’s blog post will focus on the new features for CAD and meshing within the latest release of Simcenter STAR-CCM+, version 2510. There are many new features within these topics in the new version, and we have selected three of them to explain more thoroughly and four shorter descriptions as honorable mentions.   Multi-target Boolean subtract (and speed-up for the operation)  The subtract operation is often used when creating a fluid domain, and this release has spoiled us with both faster execution time and more functionality. Subtract operations are available in both 3D-CAD and under operations within the main GUI tree-structure, and the improvements apply for the operation within the tree-structure.  When setting up a subtract operation you select input parts (parts that will be used […]
- [Setting up Buckling Solutions in Simcenter 3D](https://volupe.com/simcenter-3d/setting-up-buckling-solutions-in-simcenter-3d/): Since we have started having frost nights here in Sweden it came to me recently when I started looking over my tools required for shifting tyres on the car that I lack “trestle jacks” or any type of jack stand. Having buckling on my mind I also started wondering how the requirements regarding such equipment looked in terms of buckling dimensioning -wouldn’t want to have my hands under a 2 tonne car… A less severe example of when buckling comes into play is if you ever have had the misfortune of trying to push in a straw in a carton only […]
- [DFBI and Solution History Integration in Simcenter STAR-CCM+: Unlocking post processing options for Marine Simulations](https://volupe.com/simcenter-star-ccm/dfbi-and-solution-history-integration-in-simcenter-star-ccm-unlocking-post-processing-options-for-marine-simulations/): After years of development, Simcenter STAR-CCM+ 2502 introduces a game-changing feature that Naval Architects and CFD specialists have been requesting for years: full integration of Dynamic Fluid-Body Interaction (DFBI) with Solution Histories (.simh files). This leap forward transforms how we visualize and analyze transient simulations involving moving bodies. The Pain Historically, creating powerful animations from transient results that included DFBI bodies was severely limited. DFBI bodies couldn’t be included as inputs to Solution Histories files. We were forced to rely on bulky workarounds involving hardcopies or complex workflows to adjust viewpoints. This was extremely inflexible and often required re-running entire simulations […]
- [Simcenter STAR-CCM+ Multiphase news version 2510](https://volupe.com/simcenter-star-ccm/simcenter-star-ccm-multiphase-news-version-2510/): As is my custom, whenever a new version of Simcenter STAR-CCM+ is released, I go over and summarize the most important news for multiphase simulations. And the release of Simcenter STAR-CCM+ 2510 will not be an exception to this rule. I will go over here what we at Volupe find to be the most impactful changes and editions to multiphase simulations. Generalized phase replacement model The generalized phase replacement model is an improvement to the phase replacement model available in VOF-simulation. Where the old version was often used to remove numerical ventilation in marine simulations, by allowing the primary phase to […]
- [Faster geometry creation in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/faster-geometry-creation-in-simcenter-star-ccm/): Did you know that Simcenter STAR-CCM+ has some built-in predefined geometrical shapes that you can use to jump start your simulation? In this blog post we will highlight some of these quick steps for geometry creation to help you become even more efficient in the software. Quick geometry creation in 3D-CAD As most readers are probably aware at this point, the 3D-CAD module in Simcenter STAR-CCM+ allows you to either import or sketch and build geometry from scratch, much similar to any given CAD software. But sometimes you just want to create something very simple and standardized, and then there is […]
- [EMP porous media](https://volupe.com/simcenter-star-ccm/emp-porous-media/): In this week´s blog post we will look more in detail at the new phasic porous media compatibility with EMP. This new feature was shortly introduced here: [Simcenter STAR-CCM+ Multiphase News Version 2506 – Volupe.com]. But the TLDR is that porous media was not compatible with EMP before. Using EMP there is generally a strict interaction between the phases, usually a liquid and gaseous phase. While in a porous media the liquid interaction with the gas is secondary to the liquid interaction with the solid component of the porous media. Resistances If we look at the equation for the body force […]
- [Simcenter Amesim – Gas Dissolution and Aeration in Liquids](https://volupe.com/simcenter-amesim/simcenter-amesim-gas-dissolution-and-aeration-in-liquids/): The liquids we use in our engineering applications typically always contain some trapped gas, generally air. This gas can be dissolved within the liquid, but if pressure is decreased the dissolved gas will be released back into its natural free state to form undissolved bubbles within the liquid. This process is called degasification. For the process of introducing more air, the term aeration is also commonly used. As the liquid properties of a mixture can change significantly if gas is present in undissolved form, it is important to have methods to account for these phenomena. Both the impact of undissolved gases […]
- [Simcenter User Conference 2025 a summary](https://volupe.com/simcenter-star-ccm/simcenter-user-conference-2025-a-summary/): It’s that time of year again. The long summer days are behind us. It’s the season when routines settle in again and at Volupe, it has also become the season for another tradition: the Simcenter User Conference. Four years in a row now, we’ve gathered our community not just to talk about engineering and simulation, but to pause, recharge, and listen to keynote speakers who challenge us to think differently. These keynotes have grown into a highlight of the event. They remind us that innovation isn’t just about sharper tools and faster solvers, but also about leadership, balance, and mindset. This […]
- [Euler angles and Tumbling of badminton shuttles in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/euler-angles-and-tumbling-of-badminton-shuttles-in-simcenter-star-ccm/): Euler angles and Tumbling of badminton shuttles in Simcenter STAR-CCM+ We are back with badminton related simulations on the Volupe blog and this time we will focus on tumbling shuttles. Tumbling is a phenomenon where the shuttle is spinning heavily, and the rotation needs more than one axis to describe the motion. Tumbling motion occurs when the initial forces and the body forces (fluid and gravity forces) cannot (quickly) find a stable rotation around the axis through the center of pressure and the center of mass, giving rise to a chaotic search for equilibrium of force. This was described in a […]
- [Faster simulations with rotating bodies using Boundary Interface Caching in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/faster-simulations-with-rotating-bodies-using-boundary-interface-caching-in-simcenter-star-ccm/): Running simulations with rotating bodies typically involves the use of interfaces, along with a repeated process of interface intersection. The interface intersection process is a necessary evil, needed to establish an accurate connection between the separate regions for each time-step, and can sometimes be a noticeable bottleneck for rotating simulations. But since the release of Simcenter STAR-CCM+ 2502, there is now a way to improve the situation, with the introduction of Boundary Interface Caching. How it works Let’s start with establishing the prerequisites for using this new feature. First off, you must use Metrics-Based connectivity for the interface. Secondly, Boundary Interface […]
- [Using the Passive Scalar](https://volupe.com/simcenter-star-ccm/using-the-passive-scalar/): In this week’s Volupe blog post we will look at the Passive scalar model. How to interpret the passive scalar, how to use it and how to set it up. What is a passive scalar? It is a good question because the answer is not necessarily completely intuitive. In reality, a passive scalar is whatever you want it to be, within reasonable limits of course. The passive scalar is a user-defined variable of arbitrary value, assigned to a fluid phase or to individual particles. The “passive”-part of a passive scalar indicates that they do not affect the physical properties of the […]
- [Defining and Analysing Multiple Loadcases in SC3D More Efficiently](https://volupe.com/simcenter-3d/analysing-many-loadcases-in-sc3d-efficiently/): In many cases of dimensioning structures where service loads are in question there are numerous loadcases and combinations of these simulated to investigate which one that will have the most negative impact on structural integrity. Using service loads it is also common for stresses in the structure to lie below the yield limit so that no plastic deformation is to occur. Moreover, when dimensioning e.g. steel structures the deformations are often assumed to lie within the small deformation range, and with simulations lacking any other nonlinearities, these types of cases are ideal for the types of pre- and postprocessing capabilities that […]
- [Importing Topography to Simcenter Flomaster (GIS)](https://volupe.com/simcenter-flomaster/gis-import-in-simcenter-flomaster/): Simcenter Flomaster provides multiple options for importing your system’s geometry into the tool. Some of the benefits of working in this way include reduced model-construction time, less manual work, and the ability to reuse already created CAD geometry. Apart from importing geometrical data describing a system’s different parts, such as pipes, junctions, and volumes, an intriguing concept is to also account for variations in height or length caused by the topography of the ground which the facility is placed on. Geographic Information Systems (GIS) import capability opens for the possibility to explore multiple sites for a facility, or to determine how […]
- [Motion Preview in Simcenter STAR-CCM+: Faster, Smarter Motion Validation](https://volupe.com/simcenter-star-ccm/motion-preview-in-simcenter-star-ccm-faster-smarter-motion-validation/): Complex motions need validation of their definition prior running the computation to avoid running into simulation issues later when resources have been spent. This is particularly critical when defining the motion of multiple gears. Even for marine applications multiple motions of the rudder and propeller can become a headache to set up flawless. Until version 2410, previewing motions inside Simcenter STAR-CCM+ was possible only by running a simulation with all physics turned off. While this workaround provided a glimpse of how moving parts would behave, it came with two major drawbacks: it was time consuming, and it lacked flexibility. Now you […]
- [Spanwise force analysis in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/spanwise-force-analysis-in-simcenter-star-ccm/): Accumulated Force Table is a built-in feature in Simcenter STAR-CCM+ that is commonly used within external aerodynamics to visualize how drag or lift forces develop in the streamwise direction along a body. In this article we will demonstrate how to utilize this feature to analyze force distribution also in the spanwise direction, e.g. along the wingspan of an aircraft. Moreover, we will outline a workaround to overcome some of the inherent flaws that come into play with the Accumulated Force Table for the spanwise implementation. To demonstrate the workflow, we will use an example with a single wind-turbine blade. Spanwise lift […]
- [New features for CAD and mesh in Simcenter STAR-CCM+ 2506](https://volupe.com/simcenter-star-ccm/new-features-for-cad-and-mesh-in-simcenter-star-ccm-2506/): We are back with new blog posts on the Volupe technical blog, after the summer vacation break. The new release of Simcenter STAR-CCM+, version 2506, was released during the summer, and many great new features were introduced. If you missed Robin’s blog post about new features for multiphase flow, follow this link https://volupe.com/simcenter-star-ccm/simcenter-star-ccm-multiphase-news-version-2506/.

Both increased speed for the surface remesher and concurrent-parallel meshing for assemblies have been implemented.  Let’s […]
- [Simcenter 3D Feature Improvements in the 2506 Release](https://volupe.com/simcenter-3d/simcenter-3d-feature-improvements-in-the-2506-release/): Coming back from vacation, some of you may have missed that just at the beginning of this summer Simcenter 3D version 2506 was released (link to download). To bring you up to speed, this blog will be centred around some of the new features implemented in this version that can improve your workflows: Automatic Selection Recipes Manual Node Creation Improvements Material List Filters New Cross Field 2D Mesher STL Export of Deformed Meshes Additionally, some other features which also deserved mentioning are brought up at the end of this post. Automatic Selection Recipes Previously when using Selection Recipes, the user was […]
- [Simcenter STAR-CCM+ Multiphase news version 2506](https://volupe.com/simcenter-star-ccm/simcenter-star-ccm-multiphase-news-version-2506/): We are approaching yet another new release of Simcenter STAR-CCM+, this time it is version 2506. And as usual I will give some extra attention to the news that relates to multiphase simulations. This time around, the focus has been on automation, streamlining, and some GPU compatibility. Volume fraction Sub-stepping made default (VOF/MMP) I have been writing many times about the Implicit multi-stepping that was implemented a few years ago for Volume of fluid simulation and for the Mixture multiphase model. Where we allow for more inner iterations in relation to the volume fraction solver, to achieve a larger global time […]
- [Free surface simulations in Simcenter FLOEFD](https://volupe.com/simcenter-floefd/free-surface-simulations-in-simcenter-floefd/): In this week’s blog post we will look into simulations including several phases within Simcenter FLOEFD. We have the opportunity to model both subdomains with different fluids as well as Free surface simulations. The meaning of subdomains is domains with a wall dividing your computational domain into several domains, having the possibility to use different fluids in each subdomain. While free surface will track an interface between two phases in the same computational domain. Free surface simulations are similar to Volume of Fluid (VOF) simulations in Simcenter STAR-CCM+.  Example – Subdomains in a ball valve  In Simcenter FLOEFD you select a […]
- [Using Guyan Reduction to Create Superelements in SC3D](https://volupe.com/simcenter-3d/using-guyan-reduction-to-create-superelements-in-sc3d/): If you have ever had a simulation which was big, just a bit short of too many degrees of freedom (DOF), and you wished there was a way of simplifying it without affecting the results; Well, this blogpost could be for you. Using superelements in Simcenter 3D (SC3D) provides the chance for users to reduce the number of DOF in their models, freeing up RAM, as well as speeding up simulations without necessarily invoking a larger error in the analysis. How? Let’s have a look at how SC3D and Simcenter Nastran can solve this. Starting off: what is a superelement? (Or […]
- [HEEDS Smarter Tools for Better Surrogate Results](https://volupe.com/simcenter-heeds/heeds-smarter-tools-for-better-surrogate-results/): Introducing a Dedicated Surrogate Tab in Simcenter HEEDS Simcenter HEEDS 2504 brings a major leap forward in surrogate modelling with a dedicated Surrogates tab that centralizes all relevant tools and visualizations.

Two powerful new widgets enhance the surrogate modelling experience: Surrogate Info Widget: Enables quick assessment of the quality and characteristics of each […]
- [Extracting wall adjacent field values in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/extracting-wall-adjacent-field-values-in-simcenter-star-ccm/): In this week’s blog post we will explain how to evaluate and extract field values at a specific distance from a wall boundary. As the basis for the methodology, we will use an example where we would like to evaluate a user-defined heat transfer coefficient, with a reference temperature extracted at a specific distance from the wall. Heat Transfer Coefficient The heat transfer coefficient, often denoted , is a proportionality constant that relates the heat flux across a boundary () to the temperature difference between the wall and a reference location (in the bulk flow). This relation is expressed by Newton’s […]
- [Fluid Mixing in Simcenter Flomaster](https://volupe.com/simcenter-flomaster/fluid-mixing-in-simcenter-flomaster/): In Simcenter Flomaster it is possible to account for varying fluid concentration in a system due to mixing. Streams having different fluid composition can be mixed to form a new homogeneous mixture along the flow path, and where fluid properties, such as density, viscosity, and thermal conductivity, are derived from the concentration of each incoming fluid. Three separate fluids mixing and resulting in a fluid mixture with a new aggregated density. The mass flow rate of each stream controls the final mixture concentration in the example above. To enable this type of mixing throughout a system the simulation option “Multi Fluid […]
- [Morphing in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/morphing-in-simcenter-star-ccm/): In this week’s blog post we will take a closer look at mesh-morphing. In many situations it is necessary to include motion of one (or several) object in your simulation. Usually this is done by applying an interface between the rotating and static region, either using sliding mesh or an overset approach. There is another option to this, and that is to use morphing instead. When we morph, we let an object move and the surrounding volume mesh distort (morph) according to the motion. This post is here to understand how to use morphing and what tools we can combine with […]
- [Solution Adaptive meshing in Simcenter FLOEFD](https://volupe.com/simcenter-floefd/solution-adaptive-meshing-in-simcenter-floefd/): Adaptive mesh refinement (AMR), also called Solution-adaptive meshing in Simcenter FLOEFD, is a feature where the solver splits mesh cells based on where high gradients are located. High gradients will occur if cell size is large and/or properties in the flow field changes rapidly, like around and behind a blunt object for example. This week at the Volupe blog, we are therefore describing the concept of AMR in Simcenter FLOEFD and how to set up a simulation using this handy feature.  Starting off using a coarse global mesh you can utilize the advantage of AMR where the solver will find zones […]
- [Saving Time Starting Over - Simcenter 3D Nonlinear Restarts](https://volupe.com/simcenter-3d/saving-time-using-sc3d-nonlinear-restarts/): Moving past linear solutions and their restart capabilities as investigated in this previous post, we will today turn to Simcenter Nastran’s nonlinear solutions SOL401 and SOL402, and how their restarts function in Simcenter 3D (SC3D): In the nonlinear solutions, restarts can be used to create checkpoints in your analysis for load cases which individually could cause nonlinear effects such as plastic deformation, or large sliding in contacts to mention a few. These restart opportunities let you save computation time by not solving the same load cases several times. Additionally, they can add redundancy for long simulations if you can restart from […]
- [Pareto Plot Insights in Simcenter STAR-CCM+ Design Manager](https://volupe.com/simcenter-star-ccm/pareto-plot-insights-in-simcenter-star-ccm-design-manager/): What’s New? With the latest update to Simcenter STAR-CCM+ Design Manager, you can now fully explore how your designs perform across all Pareto ranks, not just the top rank. The new “Show All Non-Dominated” toggle adds critical depth to your analysis by revealing the broader structure of the trade-off surface. Previously, the pareto front was displayed by the points only of rank 1 of the current non-dominated front. But now, you can see designs from Ranks 1, 2, and 3, all of which are non-dominated within their respective layers.   How It Works: Use Cases Explained In multi-objective optimization, you’re often […]
- [Improve your post-processing for symmetric and periodic simulations with idealizations and transforms in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/improve-your-post-processing-for-symmetric-and-periodic-simulations-with-idealizations-and-transforms-in-simcenter-star-ccm/): In many engineering simulations it can be beneficial to utilize symmetry or periodicity to reduce model size and complexity. But for post-processing purposes, it is often helpful to visualize the full geometry. In Simcenter STAR-CCM+ you can achieve this using idealizations or transforms. This week’s blog post will outline how and when to use these features for post-processing. The concepts of idealization and transform In many cases, the concepts of idealization and transform can be used to achieve the same visual representation. But fundamentally, they differ a bit in terms of definition. An idealization in Simcenter STAR-CCM+ refers to the process […]
- [Fuel Cell Parameter Identification Workflow with Simcenter Amesim](https://volupe.com/simcenter-amesim/fuel-cell-parameter-identification-workflow-with-simcenter-amesim/): This video shows how to use the Fuel Cell Parameter Identification Tool to parameterize a Solid Oxide Fuel Cell electrochemical stack model from experimental data. With a CSV table gathering different cell voltages for different operation conditions, the tool is able to identify the parameters of the model so that the simulation results correlate with experimental data.   Author Fabian Hasselby, M.sc.  
- [A closer look at the SPH solver in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/a-closer-look-at-the-sph-solver-in-simcenter-star-ccm/): In this week’s blog post we will take a closer look at the SPH (Smoothed Particle Hydrodynamics) solver in Simcenter STAR-CCM+. As part of the multiphase capabilities the SPH solver was introduced to Simcenter STAR-CCM+ in its most rudimentary state in version 2402. We will summarize its capabilities over the different versions since release, and we will take a look at a test case and see how to work with the SPH-solver. What setups to do, mainly focusing on how the workflow might differ from what we are used to with the volume mesh based, finite volume method we all know […]
- [Benefits of Using Simcenter 3D SOL101-SOL200 Restarts](https://volupe.com/simcenter-3d/benefits-of-using-simcenter-3d-sol101-sol200-restarts/): Working with FE models, the term “restart” is often used in a concept of continuing a simulation from an already solved state of the model. The reason could either be because of the simulation crashing at a later stage, or because of nonlinearities (e.g. yield in the material) combined with loads which are to be investigated on a case-by-case basis and not be combined. Another subcase of the latter example has to do with preloads in the structure: Perhaps you have time-consuming stages where fastener loads and contacts are to develop before any other loads are applied and several independent load […]
- [Turning of badminton shuttles and flexible DFBI set up in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/turning-of-badminton-shuttles-and-flexible-dfbi-set-up-in-simcenter-star-ccm/): We are back with badminton shuttle simulations at the Volupe blog. This time we will look at how the shuttle is turning just after the hit with the racquet, which requires the moment of inertia (MOI) and center of mass (CM) to be accurate. Chalmers University of Technology is investigating these properties in a bachelor thesis project, so we will get correct values to use soon. Preliminary numbers from Chalmers and previously measured values from other institutions are used so far. In addition, we will look into the workflow of deformable flexible bodies in free motion within Simcenter STAR-CCM+.  Turning of […]
- [MRF to RBM Made Simple: Staging Motion Transitions](https://volupe.com/simcenter-star-ccm/mrf-to-rbm-made-simple-staging-motion-transitions/): The latest release of Simcenter STAR-CCM+ (2502) introduces Stages support for Moving Reference Frame (MRF) and Rigid Body Motion (RBM). This enhancement automates the transition between steady-state and unsteady simulations, streamlining workflows for applications like marine propeller design, where both types of simulations are essential for performance analysis.   In the context of marine simulations, steady-state MRF simulations are typically used to evaluate propeller thrust and torque under fixed operating conditions, while unsteady RBM simulations enable the capture of transient effects such as tip vortex interactions and wake dynamics. By automating the transition from MRF to RBM, the new Stages feature […]
- [Modeling capillary action and wall adhesion effects in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/modeling-capillary-action-and-wall-adhesion-effects-in-simcenter-star-ccm/): Did you know that Simcenter STAR-CCM+ is capable of capturing the effect of capillary action and that it allows you to mimic the behavior of hydrophilic and hydrophobic materials? In this week’s blog post we will dig into the specifics of modeling surface tension dominated flows and how to incorporate wall adhesion effects in your simulation work. Cohesion and adhesion The phenomenon of capillary action is governed by cohesion and adhesion. Cohesion is the intermolecular force between identical molecules, tying them together by mutual attraction. Since these forces are an effect from molecular bonds, the cohesive forces differ between different substances. […]
- [Gas Flow and Gas Mixtures in Simcenter Amesim](https://volupe.com/simcenter-amesim/gas-flow-and-gas-mixtures-in-simcenter-amesim/): In this article we cover how gas flow is managed within Simcenter Amesim and provide a brief overview on how the different gas library work. In Simcenter Amesim, flow in the gaseous phase is covered by several libraries, all catering to the various needs a user may have. The Pneumatic library deals with gas flow in the compressible flow regime and may be used to simulate gas containing a single species or multiple species at the same time. The library is made up of common components often found within a pneumatic systems, such as compressors, heat exchangers and pneumatic valves, and […]
- [Customize Results with Result Probes in Simcenter 3D](https://volupe.com/simcenter-3d/result-probes-simcenter-3d/): Today’s blogpost for Simcenter 3D will be about how to obtain custom results from simulation files by using Result Probes. They enable the user to define new results based on the output from the solution. Here’s how:   Create the probe Having defined a Solution you will have the option to create a Result Probe under Pre/Post→Results (tab)→Manipulation (group)→Result Probe, either before, or after solving the solution. All probes related to a specific Solution will be found under the Solution→Result Probes node in the Simulation Navigator. First when you create a new probe you are asked for a name which must […]
- [Simcenter STAR-CCM+ 2502 Multiphase news](https://volupe.com/simcenter-star-ccm/simcenter-star-ccm-2502-multiphase-news/): True to tradition, whenever there is a new release of Simcenter STAR-CCM+, there is a new set of multiphase news that we look at in our blog. And this time is no different. We’ll be looking at the Eulerian and Lagrangian multiphase news, starting with Eulerian. Simcenter STAR-CCM+ version 2502 was released a few weeks ago, and last week my colleague Christoffer wrote about news related to CAD and mesh features, presenting the new motion feature of virtual body.

- [New CAD and mesh features in Simcenter STAR-CCM+ 2502](https://volupe.com/simcenter-star-ccm/new-cad-and-mesh-features-in-simcenter-star-ccm-2502/): The first release of year 2025 for Simcenter STAR-CCM+ is here, and this week’s blog post will cover some selected features for version 2502 when it comes to CAD and mesh handling. We will for example go into extra detail for the new feature of Virtual body, which will change the way of working with moving bodies for some applications, which previously needed overset mesh or morphing. Before going into details about the handy features, it is a good idea to mention that version 2502 of Simcenter STAR-CCM+ now requires Siemens license server to handle your licensing. Siemens license server now […]
- [Fine-Tuning Calm Water Resistance Simulations for Greater Efficiency with STAR-CCM+](https://volupe.com/simcenter-star-ccm/fine-tuning-calm-water-resistance-simulations-for-greater-efficiency-with-star-ccm/): Predicting calm water resistance accurately is crucial for vessel performance optimization. In this blog we use Simcenter STAR-CCM+ to evaluate different approaches for solving the Volume of Fluid (VOF) interface, to find an answer to the question whether we can solve a standard calm water resistance simulation faster with equivalent accuracy. Simcenter STAR-CCM+ has obtained several new tools to improve accuracy and simulation time over the last years. Now it is time to evaluate these on the calm water resistance calculations. The KRISO Container Ship (KCS) served as our benchmark to systematically compare interface handling methods. Our focus was on testing […]
- [Mesh Alignment for the Trimmed Cell Mesher in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/mesh-alignment-for-the-trimmed-cell-mesher-in-simcenter-star-ccm/): In this week’s blog post we will introduce the Mesh Alignment feature of the Trimmed Cell Mesher in Simcenter STAR-CCM+, which could be good to have in your engineering toolbox. Performing Mesh Alignment on a block The default setting of the Trimmed Cell Mesher creates a mesh that is centered and aligned based on the global bounds of the geometry part. If we exemplify this using a simple block, it could look something like this: Here the default reference point for the mesh is highlighted with a red circle and as you can see it is automatically positioned in the geometrical […]
- [Flow Interaction Between Components in Simcenter Flomaster](https://volupe.com/simcenter-flomaster/flow-interaction-between-components-in-simcenter-flomaster/): In this blog article we have a closer look at how the flow and resulting pressure drop in internal flow systems behave when shorter pipes and bends are connected in close proximity to each other. In general, 1D CFD tools make use of empirical loss coefficients to determine the resistance experienced by the fluid when passing through a ball valve, a 90 [°] bend, or a flow junction, to name a few examples. These loss coefficients are typically derived from experimental or numerical methods where the flow is allowed to become fully developed before entering and after leaving a component. Ensuring […]
- [Incompressible Transient Simulation with Simcenter Flomaster](https://volupe.com/simcenter-flomaster/incompressible-transient-simulation-with-simcenter-flomaster/): In this week’s post we investigated the possibilities connected to using the transient solver in Simcenter Flomaster and look closer at how to set this up for incompressible transient cases. Simcenter Flomaster’s Incompressible Transient modelling provides the capability to model time dependent events in a real flow situation with the use of many types of system components. Some examples where this may prove useful involve investigating start-up and trip events for pumps, evaluating the dynamics of control valves, verifying surge protection measures, or simulating the filling and drainage in tanks. Understanding how quickly or slowly an event occurs within an internal […]
- [Efficient use of resampled volume in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/efficient-use-of-resampled-volume-in-simcenter-star-ccm/): In this week´s blog post we will work a bit more with post-processing, specifically the method of resampled volume. This relates to visualization and creating images to analyze. In a resampled volume we use a volumetric object to, in a semitransparent fashion, display scalar fields. Like looking at clip plane, or a surface, we can look at a volume field and evaluate our scalar field in a 3D setting. In this case we will look at a simple example with a sphere in a pipe. We will look at instant results from LES-simulation. Simulation description In the example we will use […]
- [Exploiting Tags for Templates in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/exploiting-tags-for-templates-in-simcenter-star-ccm/): In our previous article, we explored the use of filters and queries in Simcenter STAR-CCM+ to efficiently manage complex models.

- [Mastering DFBI Equilibrium in Simcenter STAR-CCM+ with optimized Settings](https://volupe.com/simcenter-star-ccm/mastering-dfbi-equilibrium-in-simcenter-star-ccm-with-optimized-settings/): Home DFBI Equilibrium Core Concept The equilibrium body motion option seeks to balance forces and moments on a 3D rigid body across specified degrees of freedom (up to six). The numerical procedure assumes a steady-state condition where forces and moments in the selected directions (translation or rotation) converge to zero. Unlike dynamic motion, this method is mathematical rather than physical, aiming for computational efficiency while preserving accuracy.   Numerical Procedure The numerical procedure for finding the equilibrium position operates iteratively: Step Size Calculation: At each time-step, Simcenter STAR-CCM+ calculates a step size for translation and rotation. Body Movement: The rigid body […]
- [Design Space Explorer - Launching a Parameter Study and Finding the Optimal Design](https://volupe.com/simcenter-3d/design-space-explorer-evaluate-only/): Home Today’s blogpost will be about the Design Space Explorer – Evaluate only study which was introduced with the 2406 release of Simcenter 3D.

- [Improved radiation workflow in Simcenter STAR-CCM+](https://volupe.com/simcenter-star-ccm/improved-radiation-workflow-in-simcenter-star-ccm/): Home Since the release of Simcenter STAR-CCM+ 2406 there is a new improved workflow for specifying radiation properties, incorporating a newly introduced continuum model called “Surface Materials”. The legacy setup for radiation properties in STAR-CCM+ required user input on emissivity, reflectivity, transmissivity and reflective specularity on each radiation boundary. This could be a very click-intensive workflow for models including many parts. The new workflow offers a more rationalized and streamlined methodology, that effectively reduces the number of clicks while also minimizing the risk of mistakes. Legacy workflow Let’s take a look at what the legacy workflow could look like as a […]
- [Marine Propulsion Modelling in Simcenter Amesim](https://volupe.com/simcenter-amesim/marine-propulsion-modelling-in-simcenter-amesim/): Home When it comes to powering boats, ships, and other watercraft, the choice of propulsion system plays a critical role for the performance, efficiency, and maneuverability of a vessel. This decision often requires a careful balancing act, where different propulsors are assessed across a range of routes, varying operating conditions, and scenarios, while also factoring in fuel efficiency and ensuring satisfactory thrust performance.
