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
