Prescribed Velocity, Interface
The Prescribed Velocity, Interface node adds a boundary condition on the top or bottom face of the shell where the velocity is prescribed in one or more directions. This condition is applicable for time- dependent and frequency domain studies. It is possible to prescribe a velocity in one direction, leaving the structure free in the other directions. The Prescribed Velocity, Interface node is a constraint and overrides any other constraint on the same selection.
To prescribe velocities on the actual material layers, use Prescribed Velocity.
Interface Selection
Select the interface or interfaces for which this constraint is to be added.

When Selected Interfaces is selected.
Only exterior interfaces can be selected.
If the same layer is selected in two Prescribed Velocity, Interface nodes being active on the same boundary, the second definition will override the previous.

All other settings for the Prescribed Velocity, Interface node are described in the documentation for Prescribed Velocity in the Solid Mechanics interface.
