Dear Vasilis,
Thanks for your advice. I have found the bug. Yes, it is from the muon
distribution. I checked the data file. There is a error in the data,
which two value are stick together, so the crash are always happed.
That is not the geometry problem. That's my problem. :)
Thank you very much.
Best regards,
Yung-Shun
