[Gmsh] Meshing .brep file fails

[David Colignon]

Hi Mikhail,

Your surface n° 1 seems to have a very strange topology.... Select it alone with Tools->Visibility->Surface 1 and 
visualize it with Tools->Options->Geometry->Visibility->Surfaces

Hence the warning and error messages:

Info    : Healing geometry (tolerance=1e-06)

and

Info    : Meshing surface 1 (BSpline surface, MeshAdapt)
Error   : The 1D Mesh seems not to be forming a closed loop
