Hi Mauro,

FLUKA is actually used in cosmic rays physics, as well as GEANT.
Some physics processes, anyway, are more accurately described in FLUKA
than in GEANT (e.g. hadronic interactions).
In general, if you want to use those codes for cosmic rays some further
programming is needed. In particular cosmic rays physics involves the
usage of spectra in a wide energy range, and to face such a condition it
is better to have a good knowledge of the code (whichever you decide to
use). For this purpose FLUKA courses are very useful.

In FLUKA there will be soon a user library for typical cosmic rays
problems, it will be called libgcr (GCR = galactic cosmic rays).
