CGNS has a bad support in free visualization software, I only know  
about visit using it, but it has an outdated version of the library  
and the implementation is far from being complete (I had to modify the  
reader plugin to be able to read cgns time dependent data). This file  
format doesn't seem to be maintained anymore in visit.
I've been using cgns for the past year, but I am now in the process of  
moving to the powerful vtk "world".

BTW, why are you guys willing to do post processing with gmsh, since  
there are already good dedicated free softwares for this purpose  
(visit,paraview,mayavi) ?
