Prescribed Acceleration, Interface

The node adds a boundary condition on the top or bottom face of the shell where the acceleration is prescribed in one or more directions. This condition is applicable for Time Dependent and Frequency Domain studies. It is possible to prescribe an acceleration in one direction, leaving the structure free in the other directions. The node is a constraint and overrides any other constraint on the same selection.

To prescribe accelerations on the actual material layers, use Prescribed Acceleration.

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