Prescribed Displacement, Interface

The node adds a condition where the displacements are prescribed in one or more directions to interfaces between material layers in the selected geometric entity (boundary, edge, or point).

If a displacement is prescribed in one direction, this leaves the material free to deform in the other directions.

To prescribe displacements to the actual material layers, use Prescribed Displacement.

Interface Selection

Select the interface or interfaces for which this constraint is to be added.

Table 6-26: Interface Selections; Prescribed Displacement, Interface
Selection	Apply To	Selection of Individual Interfaces
Boundary	When added: Exterior interfaces.	When Selected Interfaces is selected. Only exterior interfaces can be selected.
Edge, Point	When added: Top interface.	When Selected Interfaces is selected. Any interface can be selected.

If the same layer is selected in two nodes being active on the same boundary, the second definition will override the previous.

All other settings for the node are described in the documentation for Prescribed Displacement in the Solid Mechanics interface.
