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.
