BOUNDARY CONDITION FOR INTERIOR! Please help~
 
Hi,there

My 2d grid include two fluid zones, A and B. They are divide up by interface. The interface can not be set as wall because there are species flowing into B from A.

I applied a scalar equation in zone B. The boundary condition for the scalar equation is that the FLUX of the scalar equation variable at the interface of A and B.

MY PROBLEM:How do I set the bondary condition for the scalar equation?

I have an idea. Could you give any comments for it, or give me a right method for the case?

Set the interface as an interior. Then use UDF (DEFINE_ADJUST) to set the FLUX at the interface.

Thank you very much.
