// GEANT4 FF_Neutron_HP
//
// Command line options:
// -i ARG : run in batch mode from script file ARG
// -o ARG : write output to file ARG
// (defaults to FF_Neutron_HP.out)
// -n ARG : multithreading with ARG number of threads
// (only works if Geant4 was compiled with
// multithreading enables)

//! \brief Main program of the FissionFragment example
//!
//! \details Application demonstrating the Fission Fragment model as used
//! within the neutron_hp model. It demostrates the capability
//! for fission product containment by the cladding in a water
//! moderated sub-critical assembly.
//! It could also be further extended to calculate the effective
//! multiplication factor of the subcritical assembly for
//! various loading schemes.
//!
// ================ End Documentation Comments ================

// Modified:
//
// 05-08-20 ARibon
// Replaced deprecated HP environmental variables with UI commands
// 23-06-14 BWendt
// Added check for NeutronHP fission generator environment variable
