Dear Lyuhuang,
it’s not clear what is the problem you have come across.
In any case, here are some comments/advices:
1) nanometer scale is not supposed to be used with FLUKA (as stated in this answer<
http://www.fluka.org/web_archive/earchive/new-fluka-discuss/5902.html> on the mailing list by one FLUKA author)
2) for the Bragg peak characterisation, I would recommend you to use USRBIN with WHAT(2) = ENERGY (or DOSE)
3) please refer to the slides about scoring from the last introductory course<
https://indico.cern.ch/event/442634/timetable/#all>
4) I would also suggest you to go through other presentations at the course, in particular about “installation and running”,
since the message about the random file points to a running issue.
Hope this could help.
Best regards, luigi

Hi everyone!
---Please help me!here are my confusions:
***i am now simulating 100MV proton interact with 20nm 20um 20mm gold FILM to require dose data,and I also need to add some water in front of the gold film to ensure that the bragg peak is right on the flim. but as a beginner in fluka, it is not easy to handle this problem by reading manual.sometimes it reports "the random files dont exit" when i use DEFAULT-PRECISION and URSBIN USRTRACK and i dont know why this happened.
Can you give some guides on which cards is proper to solve this problem?or some reason for "random file don·t exit"
***Another confusion is the difference between URSTRACK and URSBDX:
URSTRACK:define a detector for a track-length fluence estimator
URSBDX:for define a detector for a boundary crosing fluence or current estimator
In the given example.inp, both are used to require fluence,and the result show the all region (x;0-50) results,but URSTRACK just detect the crossing fluence,how can it get the all range data?
Thanks a lots!
Best wishes!
