Hai Hantao,

Please see
http://www.fluka.org/web_archive/earchive/new-fluka-discuss/6416.html

Also note the warning under the DISCARD section of the manual:
* 4) WARNING: discarding the particles which propagate the hadronic cascade
(neutrons, protons, pions) will lead in general to unpredictable results.
