Dear Shimwell,
Thanks for this DPA example. Currently I am trying to adapt this code to be able to work with a dagmc based geometry. The inclusion of following line will infact impact the code relating to creation of tally filter and volume calculation.
openmc.DAGMCUniverse(filename='dagmc.h5m')
I have not figured out how this might work. If there is a related example that would definitely help.
Thanks and regards,
Arun
