Prescribed Normal Mesh Velocity
Use the Prescribed Normal Mesh Velocity node () to specify the velocity of the boundary in the current normal direction. The node can be used on the boundaries of deforming domains. No constraints are set on the tangential velocity.
The Prescribed Normal Mesh Velocity node should only be used in Time Dependent studies. The behavior for other studies is undefined.
