Hello! I am a new user of OpenMC and am trying to use it to model a gamma ray detector. I’m currently trying a simple simulation of a point source in the form of a Cs-137 standard source 18 cm away from the NaI(Tl) detector. I am currently using the pulse-height tally function and there is an error “ERROR: Maximum number of lost particles has been reached”. I would like to ask if anyone has any suggestions for this? Thank you!
