gschaider Assistant Moderator Bernhard Gschaider Join Date: Mar 2009 Posts: 4,225 Rep Power: 51	I'm trying to import a mesh that was generated in Gambit (in order to compare OpenFOAM with Fluent). It's a rather large room (>10m) with some thin walls in it (<1cm). These walls were not modelled by volumes but with surfaces: In Fluent the resulting faces can be assigned wall properties althoug topologically they are interior faces. When I try to import that mesh with fluentMeshToFoam I get a fatal error: --> FOAM FATAL ERROR : Trying to specify a boundary face 4(203114 207394 205234 203113) on the face on cell 185261 which is either an internal faceor already belongs to some other patch. This is face 0 of patch 16 namedbruestung_balkon. in file: meshes/polyMesh/createPolyMesh.C at line: 375. I looked at the source file and of course I could comment out that test and recompile OpenFOAM. But before I do that I'd like to ask: Would that make any sense? In other words: can OpenFOAM treat "interior faces" with boundary conditions (in that special case wall-boundaries)? __________________ Note: I don't use "Friend"-feature on this forum out of principle. Ah. And by the way: I'm not on Facebook either. So don't be offended if I don't accept your invitation/friend request
