[Gmsh] hexagonal surface tiling

[Andy Somogyi]

Hi All, 

Would anyone know if it’s possible to generate a hexagonal / pentagonal surface tessellation of a sphere? 

I’d like to be able to generate a sphere, tesselate the surface in hexagons/pentagons, then extrude the surface out in the normal direction to create a mesh of high order prisms. 

Something similar to the attached figure. 

If it’s only possible to tile the surface with quads, how would I go about extruding the 2D surface in the normal direction. 

Thanks
