Dear All
I am currently working on my MSc Thesis at Cranfield University (UK)
about Open Source and CFD, and Gmsh is one of the software packages I am
evaluating.
My problem is that the startpoint for the comparartive is a mesh
developed in Gambit. It is a quite big file, with around 500000 cells
and 34 Mb. The format file is .msh, but Gmsh is not able to open it
(even though it opens .msh).
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? Is there a way to convert
the file to something readible by Gmsh, if possible in open source?
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 ?
Cheers,
Dave

Changing the options in the characteristic length does not have any
effect, it generates exactly the same mesh. Does anyone know something
about this?
Thank you in advanced for your help
Kind regards
