Scientific paper

Three-dimensional gravitating systems of inelastically colliding masses are found in many astrophysical contexts. In this paper we present a general numerical solution for this type of problem. Simulations with a small number of particles (typically 100) can be made to represent actual systems containing many more particles simply by means of suitable scaling. The main practical problem is to establish whether two given particles collide or not: we have developed a new method, sufficiently general as to apply to any distribution of gravitational field.
