How to test the executable file

How to run example files

Here, the path to the PHITS folder is assumed to be as follows, as in When compiling PHITS-UDM

PhitsFolder=/Users/you/phits330A/phits/

Go to the examples/ folder in the folder you downloaded

cd ${PhitsFolder}/phits-udm/examples

Go to the 01/ folder

cd 01/

Run the input file (main.inp) in that folder with the executable you just compiled

Example) Executable file compiled on Mac, Intel Fortran.

../../../phits_MacIfort-udm < main.inp

or

${PhitsFolder}/phits_MacGfort-udm < main.inp

If successful, the following EPS files are generated. The particle represented by part = 900000 is a user-defined particle, and part = nu_e is an electron neutrino produced by decay from the user-defined particle.

2_production_energy.eps
3_decay_energy.eps

example file description

Recall that the sample user files were stored in the sample-code-1/ that you downloaded.

$ ls ${PhitsFolder}/phits-udm/sample-code-1/*

udm_Manager.f90
udm_int_sample1.f90
udm_int_sample2.f90
udm_part_sample1.f90
udm_part_sample2.f90

User-defined interactions are described in udm_int_*.f90 and user-defined particles in udm_part_*.f90. For details on how to create these user-defined files, see [How to use PHITS-UDM].

  • udm_int_sample1.f90

    A sample file defining interactions between electrons or positrons and atoms. An interaction is defined where the user-defined particle will be emitted from the electron or positron.

  • udm_part_sample1.f90

    Neutral particle with mass 50 MeV and lifetime 0.1 ns. Decays into 2 or 3 electron neutrinos. (unphysical, but for simplicity)

  • udm_Manager.f90

    A manager file that lists the module names of the user-defined files you wish to use.

  • examples/01/main.inp

    \(2 \times 2 \times 10 ~{\rm cm}^3\) water target and observe a new particle (kf-code = 900000) produced by the electron beam.

    • 1_flux_xz.eps

      The flux of electrons, positrons, photons, and the new particle produced by the target. Also, the flux of electron neutrinos (kf-code = 12) is produced by the decay of new particles.

    • 2_production_energy.eps

      Energy distribution of generated the new particle, etc.

    • 3_decay_energy.eps

      Energy distribution of electron neutrinos produced by the decay of the new particle.
