I am currently learning the finite element simulation of the electromagnetic field, and using the open source software Gmsh you write, because it can given the optimization of the grid generation, and easy to operate.

Hi Jianmei,

Gmsh does not output the edges with a global numbering; you'll have to do that in your code (a few lines of C++).
