Hi everyone,

i made a structure mesh using GMSH and now try to import my .msh file into openFOAM. But when I process it, it seems like openfoam goes into a dead loop. My .geo file stays below. I would appreciate it if someone could tell me what's wrong with my meshing.

I doubt there could be something wrong when I tried to use different surface to define the mesh.

Thanks!
