/INTER/TYPE1
Block Format Keyword ALE boundary nodes can be tied to Lagrangian surface to make fluid structure interaction. This way Lagrangian surface is acting as a sliding wall boundary condition.

Comments
- This interface is not compatible when the Lagrangian surface is in a rigid body.
- The Lagrangian surface normals do not need to be oriented in a specific direction.
- A small gap (positive or negative) can exist between the ALE surface nodes and the Lagrangian the surface.
- The Lagrangian surface cannot be immersed inside the fluid domain. It should always be located outside of the ALE mesh.
