Constructive Solid Geometry, The CAD-FEM Connection

A constructive solid geometry approach is adopted for FEM models that mirrors the approach in a CAD package. The topology is first divided into sub-regions using Boolean Geometry. The sub-regions are then mapped into their final shapes and a structured mesh is built. This enables the automatic meshing of all components built by the CAD package.
