Altair SimSolid®

Structural Analysis for Rapid Design Iterations

Outperforming Competitors with Accurate Results Up to 25X Faster

By performing structural analyses on fully featured CAD assemblies within minutes, Altair 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.

Multiple design scenarios can be simulated quickly under real-life conditions. Early CAD models, in any common format, can be used. Altair SimSolid tolerance of imprecise geometry means that, unlike CAD-embedded simulation tools, there is no need to simplify complex geometries before analyzing designs.

Altair SimSolid supports all typical connections (bolt/nut, bonded, welds, rivets, sliding) and analysis of linear static, modal, thermal properties, along with more complex coupled, nonlinear, transient dynamic effects. Providing the simulation power to help quicker engineering decisions, it aids development of quality products faster to beat competitors to market.

Why Altair SimSolid?

Eliminate Geometry Simplification

Altair 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.

Analyze Complex and Large Assemblies

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

Get Results in Seconds to Minutes

Altair 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.
