9: DMMOAB = "moab" - A `DM` object that encapsulates an unstructured mesh described by the MOAB mesh database {cite}`moabwebsite`.
10: Direct access to the MOAB Interface and other mesh manipulation related objects are available
11: through public API. Ability to create global and local representation of Vecs containing all
12: unknowns in the interior and shared boundary via a transparent tag-data wrapper is provided
13: along with utility functions to traverse the mesh and assemble a discrete system via
14: field-based/blocked Vec(Get/Set) methods. Input from and output to different formats are
15: available.
