[Gmsh] problem with surface displaying

[Christophe Geuzaine]

Hi Roman,

Indeed, we also noticed bugs in OpenCASCADE's surface rendering algorithm, which sometimes hangs.

The only fix for now is to use the internal Gmsh surface display mode (the "cross"): just add 

  Geometry.SurfaceType = 0;

in your file to revert to this simpler display mode.
