Shannon Entropy
---------------
Similar to Monte Carlo, :ref:`Shannon entropy
<methods-shannon-entropy-random-ray>` can be used to gauge whether the fission
source has fully developed. The Shannon entropy is calculated automatically
after each batch and is printed to the statepoint file. Unlike Monte Carlo, an
entropy mesh does not need to be defined, as the Shannon entropy is calculated
over FSRs using a volume-weighted approach.
