Finite Difference with OPENMC

Has anyone got any examples i can work with? I am trying to compare results of another method with finite difference, i’ve built a model in openmoc but the diffusion coefficient can’t be directly implemented or extracted so going to try my luck with openmc.

Thanks

Can we see the example problem you’ve written using OpenMOC

i think i may have solved the issue. will let you know if something comes up

What was the issue? What was the resolution? I’m curious if I’ve come across something similar.

Hello, if you want to compare OpenMC with a diffusion calculation where the components of the diffusion equation are tallied in OpenMC, there are some helpful hints in this thread: Different k-eff in RESULTS and calculation - #9 by mkreher13
