Hi Bernardo - Indeed, there is a little bug in Gmsh >= 2.0.0 which
prevents the mesh from displaying *while* loading a .geo file. This will
be fixed in the next release. You can test the fix by compiling
tomorrow's nightly cvs snapshot.
Meanwhile, you can use the following workaround: remove 'Merge
"somefile.msh"' from your geo file and use
gmsh somefile.msh yourgeofile.geo
instead.
