DYnamic Atmospheric Shower Tracking Interactive Model Application

DYASTIMA is a standalone application for the simulation of the showers produced in the atmosphere of a planet due to cosmic rays, based on the Geant4 simulation toolkit.

You can download it here.

Please read the manual for user instructions.
