Dear all,
Thanks for your kindly help. The problem of the non-detection of muon
tracker has been solven. The problem is the geometry problem, Now It can
take muon information in simulation! Thanks for Roesler's instrutions.
But I encountered another trouble, while I put the realistic muon
distribution in our lab. If the muon event become large, It would crash.
/home/adair/fluka/flutil/rfluka: line 311: 2645 Aborted
(core dumped) ${EXE} <$INPF 2>$LOGF >$LOGF
But if the muons are mono-directional, and be shot from the ceiling to the
liquid scintillator. It will be ok.
Attached are err and relavant file, I looked up the past posts, and found
it may be due to geometry problem. I struggle with it for days, but still
have no idea to solve it. Please give me instrucitons! Thank everyone!
This is the relavant msg,

Best regards,
