Can anybody tell me what might be wrong here..

I'm having problems whenever I try to convert a GMSH .msh file which contains a curved surface (as generated by the circle arc option in Gmsh). It generates a reasonably looking mesh in Gmsh but when I run gmshToFoam I get a whole load of the following type of error...

--> FOAM Warning : Not using gmsh face 3(21 2 20) since zero vertex is not on boundary of polyMesh
--> FOAM Warning :
From function gmshToFoam
in file gmshToFoam.C at line 799
Could not match gmsh face 3(21 2 20) to any of the interior or exterior faces that share the same 0th point
--> FOAM Warning :

Could not match gmsh face 3(3 2 21) to any of the interior or exterior faces that share the same 0th point



Viewing the resulting mesh on paraFoam shows that only the parts of the mesh enclosed by straight lines have been converted (and correctly!) but areas enclosed in one or more curved line are omitted from the mesh in paraFoam

Any ideas - I'm completely confused - I think Im defining the curves okay in Gmsh, but Im a beginner to all this, so I might be wrong!

Is Gmsh the best free mesh generator available on the net or is there something more useful for generating 3D meshes as trying to write out a complex blockMeshDict manually is making my head spin.
