[Trilinos-Users] Unique enumeration of faces in STK mesh?

[Williams, Alan B]

STK team: could one of you please reply to Mike about this? (if you didn't already)
I'm still mostly out of commission, but I think stk-mesh does provide unique face ids (but not all faces are created by default unless requested due to memory requirements).
