How to make the power distribution calculated by openmc map onto the mesh of moose?

[LeonDong1998]

Hello all！
I found a good result in the initial trial calculation process. The power distribution calculated by OpenMC can be mapped to the mesh.
But after I changed the version recently, I found that this function cannot be realized. The current power distribution requires multiple divisions of the geometry in OpenMC. I want to know how to achieve the mapping in the current version?

Hi @LeonDong1998, I'm not sure exactly what you are asking -- can you share your input files so I can try to better understand?

To me, it looks like you have a mesh tally in the image above - in which case OpenMC treats every element in the [Mesh] as a unique tally bin.

Thanks a lot！
Based on your description, I have identified the issue. In the latest version of the [Tallies], I should use MeshTally instead of CellTally.

I changed CellTally to MeshTally and the problem was solved. Thank you again！
