[Gmsh] about surface loop

[David Colignon]

Hi,

you can visualize the orientation of the surfaces (and the influence of the minus sign) by putting a non-zero value in 
Tools->Options->Geometry->Visibility->Normals box.

idem for the mesh in Tools->Options->Mesh->Visibility->Normals

Cheers,

Dave
