The hadron code is known to work well with SNOMAN and can produce nice events on the XED event display. However, because hadrons often involve large energies and various interactions can produce multiple hadrons in turn, the number of tracks needed for SNOMAN to properly handle a high energy hadron can be quite large. It is not uncommon that a ID FULL or UNABLE to PACK EVENT error is seen when using hadrons. Presumably, expanding the number of tracks SNOMAN can handle would easily fix this problem.
The FLUKA code also is not know to work well for energies below 20 MeV (no cross-section is given below these energies). Ionization and decay routines, however, still work in this regime. Future work potentially would fill in this energy gap, if necessary.
