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 Altair SimSolid rather than hours or days needed with traditional FEA tools.

SimSolid Introduction
Analyze Complex Parts

Analyze Complex and Large Assemblies 

Created to analyze complex parts or large assemblies typically not practical with traditional FEA. Altair SimSolid™ excels faced with non-uniform contact surfaces having both gaps and overlapping geometry.

Eliminate Geometry Simplification

Eliminate Geometry Simplification
Altair SimSolid's distinctive technology totally eliminates the need for geometry simplification and meshing: the two most time-consuming, and error-prone tasks involved with traditional structural analysis.

Types of Analysis

Available Analyses
Linear statics, modal, stress linearization, thermal, coupled thermal-stress, nonlinear statics (contact, material and geometrical), fatigue analysis, linear superpositioning, linear dynamics (time, frequency and random response).
