[Gmsh] Only quadrangolar mesh

[David Colignon]

Hi,

see  http://geuz.org/gmsh/doc/texinfo/gmsh-full.html#SEC8

Gmsh is not primarily a structured mesh generator: no automatic quadrilateral or hexahedral meshing algorithm is 
provided. If you want quadrangles, you have to use transfinite or extruded meshes or recombine unstructured triangular 
meshes. For hexahedra, your only choice is transfinite or extruded meshes;

The 2D structured algorithms (transfinite and extrusion) generate triangles by default, but quadrangles can be obtained 
by using the Recombine commands (see 4.2.2 Structured grids, and 4.2.3 Miscellaneous)
