In have a functional converter from the 3d-gambit mesh file format to the gmsh file format. If you send me the compressed Gambit mesh, I could send you back the gmsh mesh. Also, I have a converter from gmsh geo file to gambit journal file. However, both are programmed using linux, and I am not really allowed to give away the code (approx 1year of coding, and it includes much more than just the converter, but also solvers and a lot of junk). If you really need it more often, maybe i can try to compile it with cygwin and send you a windows executable for non-commercial use. Linux binary is more tricky, as we only use amd64 with ubuntu j* j*.
greetings, Bernhard PS: by the way, 500000 is _not_ a large mesh. Bernhard Kubicek Energy Department Electric Energy Systems Bitte beachten Sie unsere neuen Kontaktdaten!

Hi Javier, I suppose Gambit and Gmsh use .msh as an extension for mesh file, but it doesn't mean that the format of the files is the same (open both with a text editor to see the differences). I am not aware that Gmsh is able to open Gambit mesh files... Gmsh has its own format for mesh files: http://www.geuz.org/gmsh/doc/texinfo/gmsh-full.html#SEC56 > Does anyone know what the problem might be?

Gmsh can also import and export meshes in I-deas UNV, Nastran BDF, STL, Medit MESH and VRML 1.0 files format Is > the size of the file or the number of cells a limitation > > I also tried to do the mesh from scratch on Gmsh, including the > geometry. I got a mesh but if I try to refine it the program crashes. Can you send us your .geo file ?
