Gmsh is primarily an unstructured mesh generator (triangles/tetrahedra
with no predefined ordering relations between the elements). If you plan
to implement "standard" finite difference schemes, I guess you would
rather look for a structured mesh generator ("ordered"
quadrangles/hexahedra)... Gmsh can generate such meshes, but its
possibilities in this area are *very* limited (only simple transfinite
or elliptic meshes can be generated). Though, you may download the
sofware and take a look at the sixth file in the tutorial, which will
show you the possibilities of Gmsh in this area.

It is completely free. The only think we ask if you use it is to mention
it in your work.

Yes. Some examples are shown on the web page
