[Gmsh] ellipsoid

[Stephan Köhler]

Hello,
I try to build a mesh of an ellipsoid with gmsh 3.0.6, but the surface
mesh is not so pretty. I've done some research, but i couldn't find a
solution. So I hope you can help me. Some part of the code is blow (is
worked with gmsh 2.13.2).
Thank you very much,

Stephan
