Hello everyone,

I have the problem with internal surfaces in the mesh, because I don't know what BC to specify there (I tried cyclic but it didn't worked). These internal surfaces are supposed to be part of the fluid and not real physical walls. So, i want to get rid of them. Is it possible to join the internal surfaces with the rest of internalMesh?

To be more specific, the mesh was made with ICEM. Internal surfaces were introduced only for making special blocks which have different shapes and mesh densities. The mesh was stored in a fluent format and imported to OpenFoam with fluent3DMeshToFoam command. Now, I have also patches of these internal surfaces in the constant/polyMesh/boundary file but I want to get rid of them.

What do you suggest me to do? Thanks in advance!
