Altair SimSolid

Structural Analysis for Rapid Design Iterations.


SimSolid is the game-changing simulation technology for designers, engineers, and analysts. It eliminates geometry preparation and meshing: the two most time-consuming, expertise-extensive and error-prone tasks performed in a conventional structural simulation.

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

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.
