[Gmsh] FEA post-processing

[paul.carrico at free.fr]

Hi Jean-François, 

Thanks for the information's ; even if post-processing is a part of gmsh
capabilities, I've been looking for a "light" but accurate
post-processor to share results with my colleagues : gmsh is fully
adapted for that purpose 

"Y'a plus qu'à " 

Thanks 

Paul
