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 ( ).
- 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 ( ) or a slipping wall boundary condition ( ).
- To define outlet/inlet, refer to /EBCS (or material boundaries: /MAT/LAW11 (BOUND), /MAT/LAW51 (MULTIMAT)).
- Contrary to Eulerian framework, a grid formulation must be used. By default, DONEA formulation is enabled (/ALE/GRID/DONEA).
