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.
