If the seed is not set at runtime it is set automatically by the application, with a seed different for each MPI task.
See the [examples](https://www.ict.inaf.it/gitlab/icsc_g4_hpc/BoGEMMS-HPC/-/blob/main/doc/examples.md) directory for ready to use configuration and macro files.
## Geometry and physics
When downloading the BoGEMMS-HPC repository, the user finds in the [geom](https://www.ict.inaf.it/gitlab/icsc_g4_hpc/BoGEMMS-HPC/-/tree/main/geom?ref_type=heads) directory the geometry classes used by the application examples.
To create an independent application, with separated geometry and physics definition, the user must activate this option and define the path to a directory of choice. Both must defined when running cmake using:
- Activating the use of a user defined path: -DUSER_CLASSES=ON/OFF (default=OFF)
- Setting the user defined path: -DUSER_CLASSES_PATH=<path-to-directory> (all user-defined classes must be in the same directory)
If new files are added to the directory, cmake must be run again.
## Configuration keywords
The configuration file units are in **mm** and **MeV**.
