Actually, Gmsh just writes the identification numbers of "users
defined" regions to this dataset 790.
I don't know why.
As for now, it's not possible to write these region IDs to
2414 unv-dataset, but
maybe it's possible to change Gmsh code to do this.
Where can I find the description of unv format, and specifically
of 2414 unv-dataset ?
With this description one could in principle write physical
properties to an unv file and read them with libmesh meshdata class.
