Restriction: Available in Abaqus, Nastran, and OptiStruct.
For Nastran and OptiStruct, it creates RBE3 elements for the head and CBUSH element for the body. For Abaqus, it creates DCOUP3D elements for the head and element for the body. The head elements project and connect to the nodes of the adjoining shell elements.

Sealing Options

Option Action
create vector Create orthogonal vectors for each CBUSH element created during the sealing realization. These vectors are used to define the orientations of the CBUSH elements, which is important to the stiffness defined in the related PBUSH cards.
