I simulated neutron particle and set neutron detector made of li6Material, the code actually runs fine but when I start particle event to be detected it quits unexpectedly, what should I do?

To help further, we’d need to see what the output to terminal looks like, and what you’d expect to see. If it’s erroring out or saying something like “segmentation fault”, then it’s probably best to compile the application in Debug mode and then run it through a debugger like lldb to see where/why the error occurs.

this is what am getting!

this is the construction!
