GSTIRN-C is a small freeware program that simulates the movement of massfull bodies according to the cinematic and Newton's law. It uses the iteration method of Euler-Cauchy. In a most general way GSTIRN-C allows to put up to 640 bodies in space just by creating a text-file including initial position, mass, density and velocity (for further information see the readme-text).
