/BCS/WALL
Block Format Keyword Defines the sliding wall boundary condition with collocated scheme (FVM).
Boundary is enabled on time control or sensor control.

Comments
- This boundary condition is compatible with /MAT/LAW151 (MULTIFLUID) (collocated scheme).
- Boundary condition is applied on element faces only if all its nodes are in the provided set.
- A set of nodes can define faces inside the mesh (internal faces). In this case, the face becomes a new boundary while the option is enabled.
- Since the sliding wall boundary condition is defined by default on domain boundaries with collocated scheme (LAW151 (MULTIFLUID)), this option aims to block a flow and release it on a given time (instantaneous opening).
- If a sensor is defined, the Tstart and Tstop options are ignored.
