[MOAB-dev] (Un-)Expected behavior of DMMoabOutput

[Vijay S. Mahadevan]

Gerd, I'm not sure how you're verifying that the GLOBAL_ID tag is not
copied but they are.  Here's my output and they look identical, as
they should. The LoadFromFile and Output routines in DM internally
just call MOAB functions unless you pass some options and so if you
see an issue, we should be able to track this down.

Can you verify if the following commands give similar results from
your MOAB installation ?
