Hello Patrick - I'm not sure if this is the reason, but there was a
surface orientation inconsistency in all versions prior to 1.54. You can
normally solve it by defining Physical Surfaces with negative numbers,
or by upgrading to Gmsh 1.54.

Tell me if you still see this behavior in the latest version.

Thanks,

Christophe
