Hi, i have problem with physical group labels.
I open gmsh.exe and create physical surface. In geo file i see something
like this:

*Physical Surface(35) = {18, 20, 22, 24}; *

But, i need label for this surface like this:

*Physical Surface("label", 35) = {18, 20, 22, 24};*

Can i label this surface without edit geo file in text editor?


Second question:
Ok, i have geo file with physical surfaces without labels:
*Physical Surface(35) = {18, 20, 22, 24};*

can i get id for this physical surface?
If physical surface has label, i just use this function:

*Gmodel *m;*

*m->getPhysicalName(dimension, id);*

*m->getPhysicalNumber(dimension, name);*

How can i get id for surfaces without labels?

thanks in advice
