Altair SimSolid VTL03 Coupled Thermal Structural Analysis

Описание: Video by Rahul Rajan
SimSolid is a new generation of structural analysis software. SimSolid’s unique approach works directly on fully featured CAD assemblies and complex part geometry models and does not use a mesh.
The SimSolid computational engine is based on significant extensions to the theory of external approximations. External approximations are a generalization 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 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.
