Nan for value='rel_err'

Hey, I just wanted to update and thank both of you guys @Shimwell @pshriwise . I have been able to use openmc_weight_window_generator successfully and improve resolution and the relative error. It has been a few weeks, and I just forgot to update in here. Results are still preliminary, but I can see some improvement in the inboard components, which is good news. Thanks!
