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

Thanks. That's pretty much what I thought.

I figure the naive approach is O(N*log N), assuming logarithmic lookups 
in the hash table. I may try to come up with something better later.

That's a great segue to my next question. Is the canonical way to access 
these maps something like:

   PairIterRelation rel = element.relations(stk::mesh::Face)

Or is there another interface?

Thanks,
Mike
