[Gmsh] Node numbering

[Ricardo Reis da Silva]

Hi everyone,

I have recently discovered Gmsh and it seems a great mesh generator!!

I am doing some tests to see how it works in more detail but i have stumbled 
with a problem. I would like to obtain the mesh file with a very specific node 
numbering. In particular i would like the nodes corresponding to the first order 
meshing to have a sequenced numbering and after that the numbering would 
continue for the second order nodes.

Is it possible to decide the node numbering in Gmsh ? or is there any other way 
to obtain this specific numbering ?

Thank you

best
Ricardo
