Meep uses a finite-difference algorithm, not finite-elements. Hence it uses a uniform Cartesian grid, and does not have what you need if you want an unstructured mesh for FEM. There are pleny of mesh-generation codes for FEM, however. For example, the free Gmsh program (http://www.geuz.org/gmsh/) seems fairly popular. Cordially, Steven G.
