Default boundary about interface and interior
Posts: n/a
What is the difference between "interface" and "interior" boundary condition in FLUENT? I have two zones (porous media zone and channel zone) connected. Which boundary condition should be set at interface between them? Thanks.

I've your same problem and, looking for it in user's guide, I've found that interior "means that the particles will pass through the internal boundary"(19-131), but it's available only for discrete phase.

Any suggestion???
