[Gmsh] Help

[Christophe Geuzaine]

Gmsh's internal CAD module is really not designed to handle trimmed patches. For spheres there's an undocumented hack you can use: add "In Sphere{id_of_center_point}" in the definition of the ruled to force the surface to be spherical: e.g.

   Ruled Surface(20000) = {15,16001} In Sphere{1};
