inlet/outlet bc at inner wall
 

Hi,

I have an inner wall (two-sided wall) which is surrounded by a fluid and a solid domain.

I would like to have an inlet/outlet boundary condition at this inner wall. (I know it's not physically correct but I need it for my model).

I could add a momentum sink/source at the fluid cells near the inner wall via UDF, but maybe there are other ways.

Thanks in advance,

Greg

Instead of momentum source/sink I mean continuity source/sink
