Spring (Rigid)

This realization creates spring (CBUSH, CELAS1, CON3D2) elements between the shell and/or solid elements and then connects using Rigid elements (RBE2, RBE3, DCOUP) elements.

Realization Details

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.
If you specify a system, the vector will not be created.
Head Element Type
Use to choose the Head Element type (only available for OptiStruct and Nastran)
Body Element Type
Use to choose the Body Element type (only available for OptiStruct and Nastran)
Rbe3 Radius
Documentation for Rbe3 Radius can be found here.
