[Gmsh] Cannot build 3D FEM mesh for the sphere

[Mikhail Artemiev]

Hi, Alexander!
If you can read Russian, you can look at 
http://numlab.blogspot.com/2011/06/gmsh-3d.html for 
detailed step-by-step instructions on how to build 3D mesh 
in Gmsh (sphere-in-cube geometry is considered, so it's 
almost your case!).

Best regards,
Mikhail Artemiev
