Quick answer:

I've moved your post from the other thread http://www.cfd-online.com/Forums/ope...ry-face-2.html - because your problem is directly related to how you exported the mesh from GAMBIT.
That error message is imply that you have surface boundaries that are inside the mesh. These need to be treated specially, because those are usually meant to be used as baffles. The closest instructions I can remember on this topic are these: https://openfoamwiki.net/index.php/H...internal_walls
