Hello all,

I'm trying to build a mesh in GMSH and send it to OpenFOAM for simulation using their tool gmshToFoam. I've been getting a lot of "warnings" and the result is that two of my patches are not correctly populated (in fact they each own zero faces) and the defaultFaces patch has more than zero.

The warnings are of the type:
-Could not match gmsh face 3(856 858 857) to any of the interior or exterior faces that share the same 0th point
-Not using gmsh face 3(856 859 860) since zero vertex is not on boundary of polyMesh

I've read a former thread in cfd-online and tried to apply it to my .geo file (including everything into a physical group), but haven't been successful.

My experience level with gmsh is pretty low, so I apologize if this is an easy question or something that I should have picked up quickly from the previous thread.

My intention is to create a tube with the shape given in the .geo file, and have air flowing through from one end to the other (inlet to outlet).
