The three types of rigid elements are as follows:
- Rigid Bar (RBAR)
Rigid Bar with Single Dependent Nodes (Nastran CBAR elements with associated PBAR cards).
- Dependent DOF (CMA)
specifies the required degree of freedom for one end of the bar.
- Dependent DOF (CMB)
specifies the required degree of freedom for the other end of the bar.
- Independent DOF (CNA)
specifies the required Independent degree of freedom for one end of the bar.
- Independent DOF (CNB)
specifies the required Independent degree of freedom for the other end of the bar.
Enter the required degree of freedom for one end of the bar.
- Rigid Body (RBE2)
Rigid Body with Multiple Dependent Nodes (Nastran RBE2 elements).
- Dependent DOF
specifies the required degree of freedom for one end of the bar.
- Rigid Body (RBE3)
Rigid Body with Multiple Independent Nodes having weighted average of motion (Nastran RBE3 elements).
- Dependent DOF
specifies the dependent degree of freedom.
- Independent DOF
specifies the independent degree of freedom.
- Weighting Factor
specifies the weighting factor. The default is 1.
