MCNP Tally ===> Equivalent FLUKA Card

F1 ===> USRBDX

F4 ===> USRTRACK

F8 ===> DETECT

PTRAC ===> EVENTBIN

MESHTALLY ===> USRBIN

Any comment on these?

Arghya Chattaraj

I think it is not that much straight-forward. In FLUKA USRBDX will give boundary crossing quantities. USRTRACK will give track density in a particular region.
