Examples in this directory demonstrate how to make use of
the interface to FLUKA hadron inelastic physics in a G4 application.

The FLUKA interface itself is included,
and located in the FlukaInterface subdirectory.

There are 2 independent G4 examples at the process (interaction) level,
in order to study XS and final state respectively (in ProcessLevel),
and instructions at the physics list level (in PhysicsListLevel).

All examples benefit from G4H1 extension (in utils),
allowing to make any G4 histogram also compatible with Flair.

ProcessLevel/CrossSection

This example allows the study of G4 cross-sections,
and in addition, of the FLUKA hadron-nucleus reaction cross sections.
The G4HadronicProcessStore is used to access cross sections.
The resulting XS can be plotted via ROOT or Flair.

ProcessLevel/FinalState

This example shows how to simulate inelastic hadron-nucleus interactions,
using G4 or FLUKA models.
The resulting final states can be plotted via ROOT or Flair.
Note that the Geant4 run manager is not used.

PhysicsListLevel

A README.md details how to select a physics list
with hadron inelastic physics from FLUKA.
