Altair Inspire is a structural simulation platform developed especially for ease-of-use. Users can create or import CAD geometry and setup, run, and optimize both motion simulations and structural simulations all from within this single platform.

With Altair MotionSolve, you can extract loads on joints that can then be transferred into your structural simulation.

With the topology optimization available with the Altair OptiStruct solver you can determine the most structurally efficient manufacturable shape for your design.





Altair HyperMesh is a finite element modeling pre-processor that allows users to produce fine-tuned, high-quality surface meshes of their CAD geometry. With HyperMesh, you get advanced control over the type and style of meshing done on each CAD face or edge along with many automated tools to make complex meshing tasks a piece-of-cake and still get great mesh flow. With the high-quality surface meshes from HyperMesh, you can create powerful and efficient 3D meshes for use in CFD, FEA, SPH, and more!





Altair Optistruct is a structural and optimization solver used for solving static, dynamic, linear, nonlinear, topology and topography optimization problems, and more! It is most widely used where lightweight and efficient structures are needed. Great for optimizing for durability, NVH, or any rapidly developing products. Optimization types supported are topology for large design spaces, topography for thin-walled structures, or free-size for finding the best thickness distribution in machined structures or finding optimal composite laminate layups.





RADIOSS is an industry-proven structural analysis tool that specializes in explicit dynamic analysis. It can handle a high degree of structural non-linearity in dynamic loading environments with ease. A few examples where RADIOSS is utilized in an industry are automotive crash testing, fluid-structure interaction for hydrodynamic events, drop tests, forming, and fracture.





Altair SimSolid does structural simulation directly on original, un-simplified CAD assemblies. It does not create a mesh. It uses a unique multi-pass adaptive solution method where it locally enriches equations and re-solves until the desired accuracy level is reached. It is fast at running simulations on relatively large models to capture stresses and displacements to make evaluating design alternatives quick and easy. You can get results in seconds or minutes with SimSolid rather than hours or days needed with traditional FEA tools.





Altair SimLab is a multiphysics platform that allows users to build their analysis models for various types of simulation. With the analysis community moving towards CAD integrated analysis solutions, Altair SimLab introduces a convenient way to move from CAD to a multiphysics simulation platform. SimLab has a powerful automated mesher and bi-directional connectivity with SOLIDWORKS to enable users to conveniently test the performance of their products with the solvers in the Altair One suite.
