Finite Element Analysis Model

Solve structural mechanics, thermal, and electromagnetic problems with a unified workflow

The unified finite element model workflow lets you solve structural mechanics, thermal, and electromagnetic problems and switch between the types of problems. This workflow uses an femodel object and its properties to define the type of problem and all its parameters.
