I am using fluka to do the simulation with Xe + U, meaning using Xe beam to interact with U plate. The running will keep a couple of minites and then failed one by one(I used the spawn function, no mistake showed before the running). I thought it was beacause the amount of secondary particles has been too many, as a result, the similation failed with error in RAM. But in fact, my RAM is big enough(64GB). I tried other ways to solve it but all efforts failed. I worked on it for two weeks and can not find the mistake now.
I showed the input file in the attachment, could you help me with it? Thank you so much.
