Currently, all of the following conditions must be met for the particle source
to be valid in random ray mode:
- One or more domain ids must be specified that indicate which cells, universes,
or materials the source applies to. This implicitly limits the source type to
being volumetric. This is specified via the ``domains`` constraint placed on the
- Either a point source must be used, or a domain constraint must be specified
that indicates which cells, universes, or materials the source applies to. In
either case, this implicitly limits the source type to being volumetric, as
even in the point source case the source will be "smeared" throughout the
source region that contains the point source coordinate. A source domain is
specified via the ``domains`` constraint placed on the
:class:`openmc.IndependentSource` Python class.
- The source must be isotropic (default for a source)
- The source must use a discrete (i.e., multigroup) energy distribution. The
