FEM Shear of a Composite Block

Introduction
In this tutorial we analyze the shear deformation of a stiff block in a soft matrix. It demonstrates the use of BooleanFragments and CompoundFilter to create separate solids for block and matrix from two concentric cubes. This set up ensures that separate MeshRegions, Materials and Boundary Conditions can be defined for the block and the matrix. The CalculiX results clearly show the effect of of the block on the response of the matrix.
