[ Top ] [ Modules ]

NAME

module initPionBox

PURPOSE

Initializes pions for a box of pions

initPionBox/thermalInit [ Global module-variables ]

[ Top ] [ initPionBox ] [ Global module-variables ]

SOURCE

  logical, save :: thermalInit = .false.

PURPOSE

flag how to initialize

initPionBox/nDens [ Global module-variables ]

[ Top ] [ initPionBox ] [ Global module-variables ]

SOURCE

  real, save :: nDens = 1.0

PURPOSE

particle density [fm^-3]

initPionBox/ChargeSelection [ Global module-variables ]

[ Top ] [ initPionBox ] [ Global module-variables ]

SOURCE

  integer, save :: ChargeSelection = 0

PURPOSE

define the type of the charge selection:

  • 0: only pi0
  • 1: 50% pi+, 50% pi-
  • 2: 33% for +,0,-

initPionBox/pInit [ Global module-variables ]

[ Top ] [ initPionBox ] [ Global module-variables ]

SOURCE

  real, save :: pInit = 0.5

PURPOSE

initial momentum of particles [GeV/c]

initPionBox/BoostZ [ Global module-variables ]

[ Top ] [ initPionBox ] [ Global module-variables ]

SOURCE

  real, save :: BoostZ = 0.0

PURPOSE

additional boost for all particles in z-direction

initPionBox/Temp [ Global module-variables ]

[ Top ] [ initPionBox ] [ Global module-variables ]

SOURCE

  real,dimension(1:122), save :: Temp = 0.0

PURPOSE

for thermal init: temperature of every meson species in GeV, if larger than 0. otherwise this species is not initialized

initPionBox/Fugacity [ Global module-variables ]

[ Top ] [ initPionBox ] [ Global module-variables ]

SOURCE

  real,dimension(1:122), save :: Fugacity = 1.0

PURPOSE

for thermal init: fugacity of every meson species.

initPionBox/correctMovingBox [ Global module-variables ]

[ Top ] [ initPionBox ] [ Global module-variables ]

SOURCE

  integer, save :: correctMovingBox = 1

PURPOSE

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

initPionBox/initInput [ Subroutines ]

[ Top ] [ initPionBox ] [ Subroutines ]

NAME

subroutine initInput

PURPOSE

Reads input out of jobcard. Namelist 'initBox'.

initPionBox/PionBox [ Namelists ]

[ Top ] [ initPionBox ] [ Namelists ]

NAME

NAMELIST PionBox

PURPOSE

Includes the input parameters:

initPionBox/initializePionBox [ Subroutines ]

[ Top ] [ initPionBox ] [ Subroutines ]

NAME

subroutine initializePionBox(part)

PURPOSE

Initialize nucleons in a box

initializePionBox/doThermal [ Subroutines ]

[ Top ] [ initializePionBox ] [ Subroutines ]

NAME

subroutine doThermal

PURPOSE

Do the thermal init

initializePionBox/doNonThermal [ Subroutines ]

[ Top ] [ initializePionBox ] [ Subroutines ]

NAME

subroutine doNonThermal

PURPOSE

Do the non-thermal init

initializePionBox/prepareChooseCharge1 [ Subroutines ]

[ Top ] [ initializePionBox ] [ Subroutines ]

NAME

subroutine prepareChooseCharge1(nTot)

PURPOSE

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

initializePionBox/prepareChooseCharge2minus [ Subroutines ]

[ Top ] [ initializePionBox ] [ Subroutines ]

NAME

subroutine prepareChooseCharge2minus(nTot)

PURPOSE

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

initializePionBox/prepareChooseCharge2zero [ Subroutines ]

[ Top ] [ initializePionBox ] [ Subroutines ]

NAME

subroutine prepareChooseCharge2zero(nTot)

PURPOSE

prepare the random selection of the charges: (-1,0,+1) = ( 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?)

initializePionBox/prepareChooseCharge2plus [ Subroutines ]

[ Top ] [ initializePionBox ] [ Subroutines ]

NAME

subroutine prepareChooseCharge2plus(nTot)

PURPOSE

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

initializePionBox/prepareChooseCharge3 [ Subroutines ]

[ Top ] [ initializePionBox ] [ Subroutines ]

NAME

subroutine prepareChooseCharge3(nTot)

PURPOSE

prepare the random selection of the charges: (-1,0,+1) = ( 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.

initializePionBox/ChooseCharge [ Subroutines ]

[ Top ] [ initializePionBox ] [ Subroutines ]

NAME

subroutine ChooseCharge

PURPOSE

Set the charge of the particle randomly according the numbers given in the array nCharge
