Hi, I have a similar problem. However, I am doing it with 2 different zones built the exact same way (sharing topology in SpaceClaim, internal boundary condition during the meshing, interfaces created in Fluent afterwards) and one of them is working just fine while the other one doesn't allow the flow to fly through it. When you say that the interface don't fullly overlap, how can we check that it is the case ? Thanks in advance,
