Physical names when loading brep files
I was wondering how the information about physical groups/names is stored when using OpenCascade and .brep files. I would expect that when the geometry is loaded from a .brep file, we could, in principle, recover the physical names from the generating .geo file.
As an example, I use the .geo file, cylinder.geo, which labels certain entities (e.g. "channel") which I can view using options -> Geometry.
When I later load the .brep generated from this .geo file, cylinder.brep, and apply the same options, no physical names are visible. Moreover, if I mesh the geometry generated by the .brep, the physical names do not appear in my .msh2 file.
