Hi all:
I am new to OPENMC and am trying to learn how to write fixed sources for OPENMC. I’m in about learning energy distribution and a little confused. I am attaching my MCNP source card, how should the energy distribution in MCNP be written in OPENMC? Is it with openmc.stats.Tabular?
I would greatly appreciate any help in this regard. Thanks!
