[Gmsh] transfinite on complex 2d geometry

[Ruth V. Sabariego]

It is not necessary to split the surface in subsurfaces, you just have 
to indicate the corners that constitute the basic rectangle/square and 
be sure that the number of division in the now composed basic edges 
match what you want.

Have a look at tutorial t6.geo:
