Prescribed Displacement

The node adds a condition where the displacements are prescribed in one or more directions to 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 on interfaces between the material layers, use Prescribed Displacement, Interface.

Layer Selection

In the node, you cannot access individual layers. Thus the selection in this section only acts as a filter for the boundary selection.The constraint is applied all through the thickness of the shell.

Selection	All Layered Materials	Layered Material Definitions	Selection of Individual layers
Boundary	Default	Selectable	Not available
Edge	Default	Selectable	Not available
Point	Default	Selectable	Not available

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

•

For a general description of layer and interface selections, see The Layer Selection Section.

•

You can prescribe displacements with a through-thickness variation by explicitly or implicitly using expressions containing the extra dimension coordinate as described in Using the Extra Dimension Coordinates.
