I have a problem when reading a turbomachinery problem into Fluent. It is not an error as such but i think it is the reason my solution is not converging. I have analysed similar problems before (same problem, different geometries) and have never got the following comments when reading the file:

Note: Separating interior zone 27 into zones 27 and 1.

default-interior -> default-interior (27) and default-interior:001 (1)

and

Skipping zone periodic_downstream_shadow (not referenced by grid).

Does anyone have an idea what might be wrong? I checked for double faces but found none. Any help would be massivly appreciated on this.

Hi

Most likely the reason is that you merged two meshes, however, one interface remained. If you have two separate meshes, and you have TGrid, try with that because it might happen that Fluent is not reading shadow face. Open meshes in TGrid and try to merge the faces.

However, if it is a single mesh then you have faces that are not connected, i.e., the interfaces of two adjacent volumes are seprate while they must be same.

You've written that you've looked for double faces but Fluent might not be showing them.
