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.
Restriction: Available in Abaqus, Nastran, and OptiStruct.
Creates RBE2 (Nastran/OptiStruct)
or KINCOUP (Abaqus) elements for the head and the body.
There are two individual RBE2/KINCOUP elements at the head of the connection, one to
connect to the inner row of nodes, the other to connect to the washer layer nodes. The
connector location can either be on the edge of the hole, center of the hole, midpoint
in between the two holes or on the second row of nodes which form the washer layer.
