4 FLUKA modules (Fortran files)

Since several years, the FLUKA source code has been organised in "modules". This word must not be intended to have the technical meaning which it has been assigned later in Fortran 90. A FLUKA module is simply a collection of routines covering the same physics field or belonging to the same class of functionality.

In the FLUKA2011 version, there are 35 modules:

 BAMJM     :    new hadronisation package (strongly improved version of the
                original BAMJET [Rit84])
 BLOCKM    :    block data routines
 BMEM      :    the Boltzmann Master Equation nucleus-nucleus interaction
                package for nucleus-nucleus interactions below 100 MeV/u
 COMLATM   :    all geometry routines specific for combinatorial geometry
                (CG) and repetition (lattice capability) in the geometry
 DECAYM    :    all routines connected with particle decays during transport,
                including those managing polarisation or non phase-space-like
                decays for pions, kaons, muons and taus
 DEDXM     :    all routines connected with dE/dx and radiative losses of
                hadrons and muons, including delta-ray production and cross-
                sections for muon photonuclear interactions

                and interactions (except for photon photonuclear interactions,
                fluorescent X-ray and Auger production)
 EVENTQM   :    auxiliary routines for the high energy hadronic interaction
 EVENTVM   :    all routines (besides those in EVENTQM) connected with the high
                energy hadronic inelastic interaction package

 GEOLATM   :    geometry navigation and debugging routines
 KASKADM   :    general event steering, most of the relevant transport routines
                for hadron and muon transport, including magnetic field tracking,
                most of material and region dependent initialisation and source
 LOWNEUM   :    all routines concerning the multigroup treatment of "low" energy
                (E < 20 MeV) neutrons

                FLUKA86, and blank COMMON setting for scoring options

 IBMM/HPM/LINUXM/OSFM/VAXM : timing and "environment" routines. These are
                machine specific.

User oriented routines (see description in (13)):
