Hi OpenMC community,
I am currently writing my master’s thesis on Variance Reduction techniques in OpenMC, specifically studying available local variance-reduction techniques.
For this purpose, I have been trying to only tally in certain cells of my mesh, and saw that openmc.MeshFilter has a “bins” variable. To my understanding, this should be a way to pick cells in a mesh to tally in, is this incorrect? When testing this, I was unable to tally in only certain picked cells, as it would continue to tally in all cells of the mesh, is this expected behaviour?
Lastly, I saw that there is an open pull request on openmc’s GitHub, introducing Local Variance Reduction to OpenMC, does anyone know the status of this? Is it possible to get the functions introduced in this pull request?
Any insight into this would be greatly appreciated.
