GEANT4 11.1.2

Basic information

Tested on (Requirements)

  • OS base: Rocky Linux 8.5 (x86_64) \(\boldsymbol{\ge}\) 8

  • Compiler GCC 9.3.0

Installation

  1. First of all, we need to load the following modules for the compilation

    $ module load cmake-3.22.2-gcc-9.3.0-paiswui expat-2.4.6-gcc-9.3.0-nlngbc3 gcc/9.3.0 mpich/4.1_gcc-9.3.0

  2. Then, download the tar.gz file and unpack it

    $ wget https://gitlab.cern.ch/geant4/geant4/-/archive/v11.1.2/geant4-v11.1.2.tar.gz
$ tar -xvf geant4-v11.1.2.tar.gz

  3. Then, we create two directories in the same location than we unpack the tar.gz file, one for build and the other for install

    $ mkdir build_geant4 install_geant4

  4. Then we can continue with the installation

    $ cd build_geant4
$ cmake -DCMAKE_INSTALL_PREFIX=../install -DGEANT4_BUILD_MULTITHREADED=ON ../geant4-v11.1.2/
$ make -j 8
$ make install

Note

There is another flag for the cmake command, this flag is -DGEANT4_INSTALL_DATA. This flag for default is OFF and thanks to the firewall of the University, this flag doesn’t work, because it uses a protocol that this firewall doesn’t allow. But you are free to try.

  1. Now, if we need to use the data, we must install this manually as follows

    $ cd ../install_geant4/share/Geant4
$ mkdir data
$ cd data

  2. Then, we download the tar.gz files and unpack it

    $ wget https://cern.ch/geant4-data/datasets/G4NDL.4.7.tar.gz
$ wget https://cern.ch/geant4-data/datasets/G4EMLOW.8.2.tar.gz
$ wget https://cern.ch/geant4-data/datasets/G4PhotonEvaporation.5.7.tar.gz
$ wget https://cern.ch/geant4-data/datasets/G4RadioactiveDecay.5.6.tar.gz
$ wget https://cern.ch/geant4-data/datasets/G4PARTICLEXS.4.0.tar.gz
$ wget https://cern.ch/geant4-data/datasets/G4PII.1.3.tar.gz
$ wget https://cern.ch/geant4-data/datasets/G4RealSurface.2.2.tar.gz
$ wget https://cern.ch/geant4-data/datasets/G4SAIDDATA.2.0.tar.gz
$ wget https://cern.ch/geant4-data/datasets/G4ABLA.3.1.tar.gz
$ wget https://cern.ch/geant4-data/datasets/G4INCL.1.0.tar.gz
$ wget https://cern.ch/geant4-data/datasets/G4ENSDFSTATE.2.3.tar.gz
$ wget https://cern.ch/geant4-data/datasets/G4TENDL.1.4.tar.gz
$ tar xf G4ABLA.3.1.tar.gz
$ tar xf G4EMLOW.8.2.tar.gz
$ tar xf G4ENSDFSTATE.2.3.tar.gz
$ tar xf G4INCL.1.0.tar.gz
$ tar xf G4NDL.4.7.tar.gz
$ tar xf G4PARTICLEXS.4.0.tar.gz
$ tar xf G4PII.1.3.tar.gz
$ tar xf G4RadioactiveDecay.5.6.tar.gz
$ tar xf G4RealSurface.2.2.tar.gz
$ tar xf G4SAIDDATA.2.0.tar.gz
$ tar xf G4TENDL.1.4.tar.gz

Note

This process is very slow, so you must be patient.

  1. Then, we must modify one file to use this data

    $ cd ../../../bin/
$ vim geant4.sh

  2. Now, we modify lines 70 - 80 (delete ‘#’ to uncommon these lines). Then, we exit from vim and execute this file

    $ ./geant4.sh

  3. Now we are ready to use Geant4.
