Single point constraints for boundary nodes (LS-DYNA)

In the LS-DYNA environment, use the Single Point Constraint command to constrain the translational or rotational degrees-of-freedom of selected boundary nodes. You can use Single Point Constraint to define imposed motions on boundary nodes.

The Single Point Constraint command corresponds to the LS-DYNA *BOUNDARY_SPC keyword.

Where do I find it?

Application	Pre/Post
Prerequisite	An active Simulation file with LS-DYNA as the specified solver
Command Finder	Single Point Constraint
Simulation Navigator	In the appropriate solution, right-click Constraint Container→New Constraint→Single Point Constraint
