geometry. Certain modifications to the OpenMC input files are required,
however. The DAGMC geometry must be available as a ``.h5m`` file and provided
with ``dagmc_universe`` in the ``geometry.xml`` file.

~~~~~~~~~~~~~~~~~~~~~

To run a OpenMC UWUW simulation, a ``.h5m`` file containing the UWUW model
must be present in the OpenMC run directory and a ``dagmc_universe`` loaded in
must be present in the OpenMC run directory and a ``dagmc_universe`` present in
the ``geometry.xml`` like so:
::

<dagmc_universe> filename="dagmc.h5m" id="1" />

OpenMC will then load the geometry and material library when setting up the simulation.
