hi
I am simulating a room with heat source. I have attached the .geo(geometry) file "myroom.txt"
This is what I did
1.I used gmsh and did 2d mesh followed by 3d
2.saved the mesh file as .msh in buoyantPisoFoam /hotRoom
3. I ran gmsh2ToFoam utility
4.The output was


File format version: 2

Found string labels for physical regions.

In my geometry file I had declared physical surface "inlet". I am not able to find inlet in
constant/polyMesh/boundary

When I viewed the mesh using paraview. I couldnt see the internal faces.
I am attaching the geometry and the mesh generated using openfoam and gmsh. Suggestions please.
