Hi,

so far I know MMA has no implemented "mesh generator". This is not
surprising as mesh generation in general is a hard problem. There are
different approaches an you could try to implement them in MMA. A nice
overview can be found in the book:

"Generation automatique de maillages" by P.L. George (Masson, Paris,
1991).

Unfortunately I do not know if there exists an English version. Here is
also an useful Internet link:

Hope that helps,
  Andreas
