[Gmsh] issue saving bdf file in command line mode

[Miguel Morais]

Hi,

I have been trying to convert a mesh in med format to bdf format in non
interactive mode.
This mesh consists of nodes and 2nd order tetrahedrals (TET10).

The command line I used is the following:

gmsh.exe mesh.med -format bdf -o mesh.bdf -3

What happens is that the mesh is reduced to 1st order (TET4).
If I do the conversion using the graphical interface this doesn't happen.

I suppose the problem is in the command line options I used, can you
suggest the correct options?

Thanks

Miguel
