Hi,
Can you explain bit more? I manage to create a one cell thickness layer and implement my BCs in there. I think specifying a BC at an interior surface does not work as we dealing with the...

In order to implement condition (above) at the interface, needs to change the interpolation scheme or the pressure velocity coupling method (I think). I'm trying few things at the moment :) lets see...

write a UDF to give a velocity boundary condition at an interior face

I'm trying to write a UDF to give a velocity boundary condition at an interior face. The velocity condition is U.n=alpa*(C_P(c0,t0)-C_P(c1,t1)). When I'm trying to get velocity condition for C1...
