SimSolid Introduction

What is Altair SimSolid?

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.

Analyze Complex and Large Assemblies

Conceived to analyze complex parts or large assemblies not practical with traditional FEA, SimSolid excels faced with ragged contact surfaces having both gaps and overlapping geometry.

Eliminate Geometry Simplification

SimSolid's unique technology totally eliminates geometry simplification and meshing: the two most time-consuming, expertise extensive and error-prone tasks done in traditional structural analysis.


Get Results in Seconds to Minutes

SimSolid is fast, having solution times measured in seconds to minutes, typically, on a standard PC, enabling comparison between multiple design scenarios quickly and accurately.
