In brief
What is Siemens Simcenter?
Siemens Simcenter is a portfolio of software for engineering simulation and physical testing, made by Siemens Digital Industries Software. Engineers use it to predict how a product will behave before they build it: flow and heat, strength and vibration, electromagnetics, and how a whole system works together. The test tools measure the real product.
Many of the tools came to Siemens with companies it bought, among them CD-adapco (STAR-CCM+), LMS (Amesim), Mentor Graphics (FLOEFD, Flotherm and Flomaster) and, in 2025, Altair. The former Altair tools share a pool of Altair Units. The others are mostly licensed one by one, and several of them can also be used together through Simcenter X Advanced (see how Simcenter is licensed).
This page covers the simulation side of Simcenter. For its test products, such as Testlab and SCADAS, ask us or contact Siemens directly.

Meshing, structures, particles and AI
Former Altair tools, now in Simcenter
Siemens has moved Altair HyperMesh, OptiStruct, Radioss, SimSolid, Inspire, EDEM, SimLab, Feko and PhysicsAI into the Simcenter family. Volupe supported seven of them as an Altair channel partner, and you keep the same contacts for licensing, support and training.

Simcenter STAR-CCM+ or Simcenter FLOEFD: which do I need?
Choose Simcenter FLOEFD when design engineers want CFD inside their CAD tool, early in the design process. Choose Simcenter STAR-CCM+ when CFD specialists want a choice of cell types: FLOEFD meshes native CAD geometry automatically with a Cartesian immersed-boundary method, while STAR-CCM+ offers polyhedral, trimmed hexahedral or tetrahedral cells with prism layers.
How is Simcenter licensed and priced?
Siemens’ own Simcenter tools are licensed one by one, and the former Altair tools share a pool of Altair Units; for Simcenter STAR-CCM+, see STAR-CCM+ price and licensing. If your team uses several tools, Simcenter X Advanced can put them under one named-user licence (see the next question). Every setup is quoted: the price depends on the number of users, the licence term and any add-on modules, and for CFD also on the computing power you need. Tell us which tools you are considering and how your team will share access, then request a licence quote.
What is Simcenter X, and which tools does it include?
Simcenter X is Siemens’ cloud-powered simulation suite, and Volupe sells both of its offers. With Simcenter X Advanced you install the tools on your own computers or cluster, including Simcenter STAR-CCM+, Simcenter 3D, Simcenter Femap, Simcenter Amesim and Simcenter HEEDS. Each user has a named-user licence that is managed in the cloud, and solvers and tokenised add-ons draw on a token pool that your team shares. For CFD, Simcenter X HPC and remote desktop runs Simcenter STAR-CCM+ on Siemens-managed cloud hardware and is paid for with Credits; you can work in a remote desktop in your browser, or send jobs to the cloud from a licensed STAR-CCM+ on your own computer. If you choose the Europe region, Simcenter X HPC and remote desktop runs your jobs and keeps your data in Stockholm, Sweden. Volupe also runs its own HPC platform for Simcenter STAR-CCM+, Volupe X; it is a separate service from Simcenter X. Tell us which tools and how much computing you need, and we will quote your setup.
Simcenter FLOEFD or Simcenter Flotherm for electronics cooling?
Use Simcenter FLOEFD when electronics cooling is one of several flow and thermal tasks your design engineers run in CAD. Choose Simcenter Flotherm when electronics cooling is the whole job and you want a tool built for it.
Simcenter Amesim or Simcenter Flomaster: which do I need?
Use Simcenter Flomaster for pressure losses, flow distribution and surge in pipe networks, and Simcenter Amesim for the wider system around them. The two can also run together through FMI, so you do not always have to choose.
When is 1D system simulation enough, and when do I need 3D CFD?
1D is enough when the question concerns the system as a whole: line and pump sizing, flow balancing or pressure surge. Move to 3D CFD when you need the detailed flow field in a single part, such as a valve body, manifold or heat exchanger.
My Altair licence is up for renewal. What do I do?
Siemens has moved Altair HyperMesh, OptiStruct, Radioss, SimSolid, Inspire, EDEM, SimLab, Feko and PhysicsAI into the Simcenter family, so the tools now carry Simcenter names, such as Simcenter HyperMesh. Volupe supported seven of them as an Altair channel partner, and you keep the same contacts for licensing, support and training. Tell us your current setup and renewal date, then request a licence quote.
