Accessing the numbering of surfaces for a given volume from script file
Dear Gmsh developers,
I would like to know if there is a way to know the numbering of the surfaces for a given volume using only the script file .geo.
For instance, if I generate a box in the opencascade kernel, how can I access the numbering of its surfaces? I really would like to know the numbering so as to apply some Periodic Surface command using only the script file .geo.
Thanks in advance.
Best Regards, M. Elsawy
