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.

Layer Selection

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

Table 6-6: Layer Selections; Prescribed Displacement, Interface
Selection	All Layered Materials	Layered Material Definitions	Selection of Individual Interfaces
Boundary	No	Selectable	Top and bottom faces can be selected
Edge	No	Selectable	All interfaces can be selected
Point	No	Selectable	All interfaces can be selected

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