Keff value for individual cells

User Support
1

I’m new in OpenMC. I tried to run a depletion calculation on a hexagonal assembly (similar to the example) i used

diff_burnable_mats = True

it produced so many materials with many id’s. How can i know which mat files belongs to which cell??(position inside the assembly) also,

I can plot & see the changes of concentration with burnup for those materials with different id’s individually. Can i find the Keff value for each individual cells inside that assembly as well?

By definition, k-eff is a global parameter so there’s no way to obtain a value for individual cells. If you wanted the k-infinity value for a given assembly, you’d have to create a separate single assembly model (with appropriate boundary conditions) and use the depleted compositions.

As far as identifying which material corresponds to what position, I would recommend using our plotter GUI to explore your model.
