:attr:`~openmc.Settings`, the rest of the problem can be defined as normal. When
running, note that the second iteration and beyond may be several orders of
magnitude slower than the first. As the weight windows are applied in each
iteration, particles may be agressively split, resulting in a large number of
iteration, particles may be aggressively split, resulting in a large number of
secondary (split) particles being generated per initial source particle. This is
not necessarily a bad thing, as the split particles are much more efficient at
exploring low flux regions of phase space as compared to initial particles.
