What is Simcenter HyperMesh?
Simcenter HyperMesh, formerly Altair HyperMesh, is a finite element modelling environment from Siemens Digital Industries Software. Engineers use it to import CAD, mesh, assemble and connect large models, set them up for Simcenter OptiStruct or another solver, and review the results. Python APIs let teams automate repeated steps.
Import, classify and join CAD assemblies automatically, then mesh them with batch meshing and reusable mesh controls
Define bolts, welds and seams as connectors, and realise them with pretension, contacts or heat-affected zones where the analysis needs them
With the Simcenter PhysicsAI add-on, train AI models on earlier results inside HyperMesh and predict new designs up to 1,000× faster than a solver run, according to Siemens

Capabilities
From CAD assembly to solver-ready model
Large-assembly model build
Import, classify and join CAD assemblies automatically, then manage subsystems and configurations as the design changes. Since 2026.1 you can check models in and out of Teamcenter inside the Simcenter HyperMesh interface. Review results in HyperMesh, or in Simcenter HyperView, Siemens' separate post-processing environment.
Meshing from shells to hexa
Create surface, tetra, solid map hexa, shrink wrap, acoustic cavity and SPH meshes, and extract midsurfaces for shell models. Save mesh controls and reuse them in other models, or let BatchMesher mesh a large assembly automatically. HyperMesh also creates CFD meshes; for dedicated CFD work, Siemens sells Simcenter HyperMesh CFD as a separate product.
Connectors, welds and crash set-up
Model welds with heat-affected zones and assess the connections for fatigue and durability. Bolt connectors generate solid elements, pretension and contacts, and since 2026.1 line connectors include a Seam Quad RBE2-RBE3 type. For crash and safety, position dummies, seat belts and airbags in a solver-agnostic workflow.
Automation, Python and AI
Python APIs let you script repeated steps and connect in-house tools, and built-in tools turn clicks into code. Export templates write to proprietary solver formats. The Simcenter PhysicsAI add-on trains on your earlier results inside HyperMesh, and Retrieve with ShapeAI finds similar meshed parts in your library.

Questions about Simcenter HyperMesh

We reply within one day.
How is Simcenter HyperMesh licensed, and what does it cost?
Siemens still describes Altair Units on its website: a subscription model in which units are drawn from a shared pool while a tool is in use and then returned, with access to more than 180 Altair and partner products. We quote each set-up individually, depending on the number of engineers, the licence term and add-ons such as Simcenter PhysicsAI. Running Altair HyperMesh today? Tell us your set-up, solvers and renewal date, then request a licence quote.
What changed for Altair HyperMesh users?
Siemens completed the acquisition of Altair on 26 March 2025. With the June 2026 release, former Altair products joined Simcenter, and Altair HyperMesh became Simcenter HyperMesh; from December 2026, Simcenter has two releases a year, in June and December. Altair's support services have moved to the Siemens Support Center. If you bought HyperMesh through Volupe, which supported it as an Altair channel partner, your Volupe contacts for licensing, support and training stay the same.
Which solvers does Simcenter HyperMesh work with?
Simcenter HyperMesh is not tied to one solver. Its documented solver interfaces include Simcenter OptiStruct, Simcenter Radioss, Nastran, Abaqus, Ansys, LS-DYNA, PAM-CRASH and Permas, and Siemens says its crash and safety workflows are proven with Simcenter Radioss, LS-DYNA and PAM-CRASH. Export templates write models to user-defined formats for proprietary solvers. Ask our engineers about your solver and version.
How does Simcenter HyperMesh compare with Femap, SimLab and Simcenter 3D?
All four build finite element models, with different strengths. Siemens positions Simcenter HyperMesh for large geometries and assemblies and highlights its Python APIs. Simcenter Femap is a CAD-independent, Windows-native pre- and post-processor, sold alone or with Simcenter Nastran. Simcenter 3D integrates CAE pre- and post-processing with geometry tools and links analysis models to design data. Simcenter SimLab is a process-driven multiphysics environment that simulates directly on updated CAD geometry. Ask our engineers which fits your models.
Can Simcenter HyperMesh be automated with Python?
Yes. Siemens describes an open architecture with Python APIs for connecting Simcenter HyperMesh to existing systems and in-house tools. Built-in automation tools convert clicks into code, so a task you do by hand can become a reusable script. You can also build custom utilities inside the interface, add solver input translators and write export templates for proprietary solvers. Ask our engineers about automating your workflow.
Can Simcenter HyperMesh be used for CFD?
Simcenter HyperMesh includes CFD meshing among its meshing tools. For dedicated CFD work, Siemens offers Simcenter HyperMesh CFD, a separate solver-neutral product for geometry preparation, meshing and post-processing; it is not a solver and is used with standalone CFD solvers. If you want meshing, solving and post-processing in one tool, Siemens describes Simcenter STAR-CCM+ as a fully integrated end-to-end CFD solution.
Does Volupe offer Simcenter HyperMesh training?
Yes. Our introductory Simcenter HyperMesh course takes 8 hours and covers basic geometry creation, midsurfaces and 2D shell meshing, surface editing, 1D and 3D meshing, assemblies, metadata and connectors, and linear static and eigenmode analysis with Simcenter OptiStruct. Dates and the course fee are on our training page, and we run customised training on site or online for companies. Ask about Simcenter HyperMesh training.
