Altair SimSolid is structural simulation that skips the mesh. It runs analysis directly on full, un-simplified CAD assemblies — including small features, fasteners and contacts that traditional FEA forces you to defeature — and returns results in minutes rather than hours. That makes it a natural fit for design engineers who need to validate and iterate without specialist pre-processing.
Altair is now part of Siemens, and DDSPLM delivers the combined Siemens Simcenter and Altair simulation portfolio across India — with local licensing, training and engineering support.
Why teams adopt SimSolid
- No meshing — eliminates the geometry cleanup and meshing step that dominates a conventional FEA workflow.
- Handles real assemblies — thousands of parts, bolted and bonded connections, and contact resolved automatically.
- Fast iteration — analyse design variants in minutes, so simulation can keep pace with the CAD cycle instead of trailing it.
- Accuracy on demand — refine solution accuracy locally on regions of interest rather than re-meshing the whole model.
Analysis types
- Linear and non-linear static stress
- Modal / natural frequency
- Linear dynamics — frequency response, random and transient
- Steady-state and transient thermal, plus thermal-stress coupling
Where it fits
SimSolid is ideal for early design exploration and rapid what-if studies on full assemblies. When you need detailed, mesh-controlled correlation — crash, fatigue, advanced non-linear — move the model into HyperMesh and the solvers in HyperWorks. Many teams use both: SimSolid to narrow the design, HyperWorks to sign it off.
