Dear Haoyu,
I see that you are using a custom source file that I would need
to be able to reproduce your case. If you send it, I can give you
more details...
By looking at the input file, when comparing USRBDX and USRTRACK
estimators in Fluka I think you might be running in the same
problems discussed in these other two messages:
