FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry
is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.
This realization type is used for modeling roll hemmings, where the outer shell is bent
around the inner shell. The inner shell is connected to the outer shell on one side with
simple hexa adhesive, and the other side is connected with RBE2 elements. A definable
orientation node decides which side the hexa adhesive should be used. This line
realization type is capable of connecting three layers that contains two components.
