Hello to everyone.  
Whenever I convert a file from msh to pyfrm, the program shows errors such as _KeyError pyfr 7, 4348_ or similar. Boundary conditions have been adjusted on gmsh and I am using a 4.108 ASCII version 4 format. PyFR version is 2.0.

Any idea?  
Regards

Can you please post your .geo file (or .msh if you do not have a .geo file) and the _exact_ backtrace.

Regards, Freddie.

Thanks fdw, I solved the problem simply ticking _ **options-mesh-general-recombine all triangular meshes** _ on gmsh. The problem has been involved normals orientation.
