Altair SimSolid Simulation

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.

Altair SimSolid Simulation

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.

Altair SimSolid Simulation

Design Confidently

SimSolid is incredibly accurate, it allows you to predict product performance and uncover any costly flaws or areas of improvement early on in the design process.

Altair SimSolid Simulation

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.
