[Gmsh] Save surface normals in the mesh file

[Umut Tabak]

Hi,

I checked the list archives for some questions asked for surface normals 
but could not get the exact answer that I am looking for.

Is there a way to save the normals of a surface in the global 
coordinates system to a mesh file. Showing the normals on the elements 
of a mesh is possible with the "Mesh.Normals = 50", but is that possible 
to somehow save this normal information into the mesh file to be able to 
read that from a user code.

Best,

Umut
