Enforced Displacement
This tool is used to define enforced translational and rotational displacement constraints.
Description
- Enforced constraints can be applied on nodes / faces / edges.
- The enforced constraint can be defined with respect to a local coordinate system.
- Varying enforced displacement constraints can be defined by using
displacement table. We can import table data using a text file with data
separated by comma or space.
