Overlapping Cells

Hello everyone, I am running GFR Modified Candle scheme and it can be used running up to 10 years but when I enable geometry_debug=True it has overlap in cell 12, 11. How do I handle that?



Hi Tsania, welcome back to the community.
since openmc has said that there are overlapping cells in Universe 4 (cells 11 and 12), you can investigate those cells.
I usually check my geometry.xml file to find which regions that overlapping each other in my cells because I can see the cell ID in geometry.xml and find which part of my model has the wrong region definition.

I think these tips can help you
