I am doing a short project for a group in radiation oncology introducing GEANT4. What I'm trying to do is write the most basic program possible that can be used as a learning aid or springboard. Purely what comes before analysis, histograms even visualisation.
My program has only the three mandatory user-defined classes (geometry, physics, and generation). In this way it's similar to novice example 1. The main is almost identical.
It's simply a box of water inside a mother (vaccum) volume. There is a particle source that shoots 100keV gammas and there are secondary electrons. This is all described through the three classes above.
Are these the only classes I need to define for such a bare bones program? If I need others what are they? What output can I expect if tracking, run and event verbosities are all set to 1 in the main?
Thanks all Tim
