NAME

program GiBUU

PURPOSE

This is the main file of the Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) code. It steers the whole simulation, including initialization, time evolution (propagation & collisions) and analysis.

BUGS

Please report bugs and suggestions for improvements to gibuu@projects.hepforge.org.

GiBUU/realParticles [ Global module-variables ]

[ Top ] [ GiBUU ] [ Global module-variables ]

SOURCE

  type(particle),Allocatable :: realParticles(:,:)

PURPOSE

The particle vector: real particles

NOTES

  • First index : ensemble
  • Second index : position within ensemble

GiBUU/pertParticles [ Global module-variables ]

[ Top ] [ GiBUU ] [ Global module-variables ]

SOURCE

  type(particle),Allocatable :: pertParticles(:,:)

PURPOSE

The particle vector: perturbative particles

NOTES

  • First index : ensemble
  • Second index : position within ensemble

GiBUU/targetNuc [ Global module-variables ]

[ Top ] [ GiBUU ] [ Global module-variables ]

SOURCE

  type(tNucleus),pointer :: targetNuc => NULL()

PURPOSE

Target nucleus

GiBUU/projectileNuc [ Global module-variables ]

[ Top ] [ GiBUU ] [ Global module-variables ]

SOURCE

  type(tNucleus),pointer :: projectileNuc => NULL()   ! Projectile nucleus

PURPOSE

Projectile nucleus

GiBUU/initConfig [ Subroutines ]

[ Top ] [ GiBUU ] [ Subroutines ]

NAME

subroutine initConfig(energyRaiseFlag)

PURPOSE

  • Initializes starting configuration for particles in each run.
  • Here we have some "select case(eventType)": for each eventType different subroutines take care of the proper initialization.
  • The vectors realParticles and pertParticles are allocated.

INPUTS

  • logical :: energyRaiseFlag -- if (true) then we raise the bombarding energy (used to perform an energy scan)

GiBUU/setUpTarget [ Subroutines ]

[ Top ] [ GiBUU ] [ Subroutines ]

NAME

subroutine setUpTarget(doUpdateEnergies)

PURPOSE

Initialize the test particles representing the target nucleus

INPUTS

  • logical, OPTIONAL :: doUpdateEnergies -- Flag to indicate, whether 'updateEnergies' should be called

OUTPUT

The particle vector realparticles is modified, also global arrays connected with this.

GiBUU/run [ Subroutines ]

[ Top ] [ GiBUU ] [ Subroutines ]

NAME

subroutine run

PURPOSE

Propagate a given realParticle and pertParticle vector according to the BUU equations.

GiBUU/analysis [ Subroutines ]

[ Top ] [ GiBUU ] [ Subroutines ]

NAME

subroutine analysis(finalizeFlag,beforeRUN)

PURPOSE

Analyze output of run.

INPUTS

  • logical :: finalizeFlag -- This flag signalises that the last run of one energy was taking place.
  • logical :: beforeRUN -- Flag to indicate, whether this routine is called before or after "run" is called. Makes it possible to produce some analysis-output of the particle vector directly after its init.

GiBUU/finalCleanup [ Subroutines ]

[ Top ] [ GiBUU ] [ Subroutines ]

NAME

subroutine finalCleanup

PURPOSE

Clean up all "global" memory. Deallocates particle vectors and projectile/target nuclei and calls cleanup routines in several modules.
