SimSolid is structural analysis software developed specifically for design engineers. It eliminates geometry simplification and meshing, the two most time consuming and expertise extensive tasks done in traditional FEA.

Moreover, SimSolid can analyse complex parts and large assemblies not practical with traditional FEA and do it efficiently on a desktop class computer. Both fast and accurate, SimSolid controls solution accuracy using a unique multi-pass adaptive analysis.

Technology Overview

The SimSolid computational engine is based on breakthrough extensions to the theory of external approximations. External approximations are a generalisation of Finite Element Method (FEM) in terms that:

  • absolutely arbitrary geometrical shapes can be used as “finite elements”
  • basis functions which approximate field of interest in the part volume can be of arbitrary class and are independent of the volume shape
  • SimSolid does not use the point-wise degrees of freedom (DOF) inherent in traditional FEA. SimSolid DOF are functionals with geometrical support in the form of volumes, areas, line clouds, and point clouds. This provides the ability to handle geometrical imperfections, as well as assembly contact imperfections like gaps, penetrations and ragged contact areas.

SimSolid controls solution accuracy using multi-pass adaptive analysis.  Adaptivity can be defined on a global or part local basis and adaptivity is always active. The SimSolid methodology is fast and efficient.  It provides superior performance metrics for computational time and memory footprint that allow very large and/or complex assemblies to be solved quickly on desktop class PC’s.
