Comments

There is no convection through a boundary face.
With a collocated scheme (/MAT/LAW151 (MULTIFLUID)) there is by default a slipping wall boundary condition ( $υ_{n} \cdot n = υ_{w a l l} \cdot n$ ).
With a staggered scheme (all material laws, except /MAT/LAW151) velocity must be fixed with /BCS option at boundary nodes. You can define either a solid wall boundary condition ( $υ_{f} = υ_{w a l l}$ ) or a slipping wall boundary condition ( $υ_{f} \cdot n = υ_{w a l l} \cdot n$ ).
To define outlet/inlet, refer to /EBCS (or material boundaries: /MAT/LAW11 (BOUND), /MAT/LAW51 (MULTIMAT)).
