switch to indicate, whether a correction of the momenta after initialization should be done to enforce vanishing 3-momenta. possibilities are:

  • 0 : no correction
  • 1 : global correction
  • 2 : per ensemble correction

initBox/initInput [ Subroutines ]

[ Top ] [ initBox ] [ Subroutines ]

NAME

PURPOSE

Reads input out of jobcard. Namelist 'initBox'.

initBox/Box [ Namelists ]

[ Top ] [ initBox ] [ Namelists ]

NAME

NAMELIST Box

PURPOSE

Includes the input parameters:

initBox/initializeBox [ Subroutines ]

[ Top ] [ initBox ] [ Subroutines ]

NAME

subroutine initializeBox(part)

PURPOSE

Initialize nucleons in a box

initializeBox/doThermal [ Subroutines ]

[ Top ] [ initializeBox ] [ Subroutines ]

NAME

PURPOSE

Do the thermal init

initializeBox/doThermalGlobal [ Subroutines ]

[ Top ] [ initializeBox ] [ Subroutines ]

NAME

subroutine doThermalGlobal

PURPOSE

Do the thermal init

initializeBox/doNonThermal [ Subroutines ]

[ Top ] [ initializeBox ] [ Subroutines ]

NAME

subroutine doNonThermal

PURPOSE

Do the non-thermal init

initializeBox/prepareChooseCharge1 [ Subroutines ]

[ Top ] [ initializeBox ] [ Subroutines ]

NAME

subroutine prepareChooseCharge1(nTot)

PURPOSE

prepare the random selection of the charges: (-2,-1,0,+1,+2) = ( - , - , 100%, - , - )

initializeBox/prepareChooseCharge1minus [ Subroutines ]

[ Top ] [ initializeBox ] [ Subroutines ]

NAME

subroutine prepareChooseCharge1minus(nTot)

PURPOSE

prepare the random selection of the charges: (-2,-1,0,+1,+2) = ( - , 100%, - , - , - )

initializeBox/prepareChooseCharge1plus [ Subroutines ]

[ Top ] [ initializeBox ] [ Subroutines ]

NAME

subroutine prepareChooseCharge1plus(nTot)

PURPOSE

prepare the random selection of the charges: (-2,-1,0,+1,+2) = ( - , 100%, - , - , - )

initializeBox/prepareChooseCharge2minus [ Subroutines ]

[ Top ] [ initializeBox ] [ Subroutines ]

NAME

subroutine prepareChooseCharge2minus(nTot)

PURPOSE

prepare the random selection of the charges: (-2,-1,0,+1,+2) = ( - , 50%, 50%, - , - ) If the total number of particles is not even, the number of neutral particles is increased by one

initializeBox/prepareChooseCharge2zero [ Subroutines ]

[ Top ] [ initializeBox ] [ Subroutines ]

NAME

subroutine prepareChooseCharge2zero(nTot)

PURPOSE

prepare the random selection of the charges: (-2,-1,0,+1,+2) = ( -, 50%, - , 50%, - ) If the total number of particles is not even, the number of negative particles is increased by one, thus the symmetry is broken (but who cares?)

initializeBox/prepareChooseCharge2plus [ Subroutines ]

[ Top ] [ initializeBox ] [ Subroutines ]

NAME

subroutine prepareChooseCharge2plus(nTot)

PURPOSE

prepare the random selection of the charges: (-2,-1,0,+1,+2) = ( -, - , 50%, 50%, - ) If the total number of particles is not even, the number of neutral particles is increased by one

NAME

subroutine prepareChooseCharge3(nTot)

PURPOSE

prepare the random selection of the charges: (-2,-1,0,+1,+2) = ( - , 33%, 33%, 33%, - ) If the total number of particles is not dividable by 3, the number of neutral or the number of both charged states is increased by one in order to get the total number of particles, but always in charge neutral sum.
