Description

Garfield garfieldgpp example adapted to Virtual Monte Carlo.

It demonstrates:

Integration of Garfield simulation model in Geant4 VMC simulation; Garfield model is not used when running the example with Geant3.

See also the original Garfield example description at: http://garfieldpp.web.cern.ch/garfieldpp/examples/geant4-interface/

Compilation:

The example requires Garfield installation; the following CMake options have to be added in the CMake configuration:

  -DGarfield_DIR=path_to_garfield_installation
  -DGarfield_INC_DIR=path_to_garfield_source/Include

Macros

For running example with G4:

   load_g4.C       - macro to load the libraries to run the example with Geant4
   run_g4.C        - macro for running example
   g4Config.C      - configuration macro for G4 with native geometry navigation (defaullt)
   g4tgeoConfig.C  - configuration macro for G4 with TGeo geometry navigation
   set_g4_vis.C    - setting Geant4 visualization (called by run_g4.C)
   g4config.in   - macro for G4 configuration using G4 commands (called from g4Config.C)
   g4config2.in  - macro for setting after initialization
   g4vis.in      - macro for G4 visualization settings (called from set_g4_vis.C)

For running example with G3: (Note that Garfield is not used with Geant3 simulation.)

   load_g3.C      - macro to load the libraries to run the example with Geant3
   run_g3.C       - macro for running example
   g3tgeoConfig.C - configuration macro for G3 with TGeo geometry
   set_g3_vis.C   - setting Geant3 TGeo visualization (called by run_g3.C)

To run example

The environment variable HEED_DATABASE pointing to /garfield/Heed/heed++/database directory has to be set.

  With G4:
  root[0] .x  load_g4.C
  root[1] .x  run_g4.C

  With G4 + TGeo navigation:
  root[0] .x  load_g4.C
  root[1] .x  run_g4.C( "g4tgeoConfig.C");

  With G3 + TGeo:
  root[0] .x  load_g3.C
  root[1] .x  run_g3.C
