Enforced displacement constraint

An enforced displacement constraint applies a known displacement to geometry or FE entities, depending on the type of constraint.

You can apply this type of constraint	To this geometry or FE entity
Magnitude and Direction****Component	curvepointmesh pointpolygon facepolygon edgenode
Face Normal	curvepointmesh pointpolygon facepolygon edgeelement

Note:

When you define an enforced displacement constraint on geometry, a local coordinate system is created and applied to the underlying nodes. If local coordinate systems already exist at these nodes, the constraint's coordinate system may overwrite them. For example, if you define a constraint on a location where spring elements are defined, the constraint's coordinate system may overwrite the spring element definitions.
