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 RBE2/KINCOUP head element that connects to the washer layer nodes only connects to every other node on the washer layer. 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.
