[Gmsh] File size limit in gmsh?

[Christophe Trophime]

Hi,
trying to create a mesh from a "template" geo file I append to notice
that I cannot create mesh file larger than 2 Gb. As I run gmsh (1.65) on
Linux FC5 I think that this limit is no longer due to the system (kernel
2.6.xx). Is this limitation really specific of gmsh?

I also wish to make gmsh able to write some other mesh file format
(especially for freefem++ and some cfd codes like Dolfyn, gerris, ...) .
Is there a simple way to tell 2D and 3D meshes when it comes to write
the mesh data to file (the only way I find so far is to look for
volumes). I also need to write the vertices nodes list as follows :

x y bc_id

How can I simply retrieve the boundary id (bc_id) for the vertices?


Best regards
