I believe that the mapping of names to integer labels is not maintained in the loading process (you mean this bit, right?):

$PhysicalNames
7
2 1 "Surf1"
2 2 "Surf2"
2 3 "Encast"
2 4 "Press"
2 5 "Surf5"
2 6 "Surf6"
3 7 "Vol"
$EndPhysicalNames

I don't know enough (anything) about the VTK output to know what is output for viz.
