[Gmsh] export mesh from .geo file

[Ricardo Gomez Bardon]

Hello,
I would like to include a command in my .geo script to export the mesh, but I can't find how to do it.
I am interested in exporting it in .unv format, and I would also need to activate the option "Save groups of nodes", and deactivate "Save all".

Is there a way to do this?

In case it wouldn't be possible, I am trying to do it from the command line, using the following expression I found online, but for some reason it is not creating the output file


gmsh myfile.geo -3 -o myoutput.unv


Many thanks in advance for your help,

Ricardo
