Hi OpenMC forum,

I am currently finishing my master’s degree where I utilize OpenMC and its’ variance reduction techniques, specifically the Weight Window Generator function. For this purpose, I was wondering if it was possible to extract the weight bounds of the Weight Windows generated by this function?  
(The counterpart to WeightWindows “lower\_ww\_bounds” variable)

Any help is appreciated!

Best Regards,
