@paulromano @gridley @amandalund Hi,When I tried to merge this code, I encountered the following errors in the GitHub automatic process : File "/home/runner/work/openmc/openmc/openmc/lib/core.py", line 143 in calculate_volumes File "/home/runner/work/openmc/openmc/openmc/model/model.py", line 923 in calculate_volumes File "/home/runner/work/openmc/openmc/tests/unit_tests/dagmc/test_model.py", line 144 in test_model_differentiate_depletable_with_dagmc This is weird because I haven 't changed the calculate_volumes function. And I did not install the dagmc library locally. Is there any suggestion that can help me further locate the error ? I will be very grateful!

According to the CI run, this is a formatting error. Even if you did not change a specific function within a file, if that file was incorrectly formatted before your change (grandfathered in from before CPP formatting was checked), then you change something else, I believe that may be a cause of your problem. However I'm not seeing any changes to core.py in this PR which is unusual.

Firstly I would suggest merging against the main branch or rebasing your changes on it. Secondly, make sure you have clang-format installed (it has to be the exact same version number!) then try running that on all the files that are having an issue. Lastly, this is the type of issue chatgpt or its brethren should be able to solve well, so that would be where I recommend you take any issues next.

Good luck!
