In the process of modeling the behavior of complex physical systems at the molecular level is often necessary preliminary synthesis of complex objects, consisting of a large number of interacting particles. As these objects can act as sophisticated molecular and crystalline structure of condensed matter. Real crystals  do not have a regular crystal lattice. They always found violations of the periodicity of the atomic arrangement. Therefore, description thereof as regular shapes is not always possible. Crystallization of substances based on the principle of minimum energy: when the atom interacts with other atoms, it loses energy, thereby making it possible to leave the interaction field. In the discrete- event simulation  is possible to construct such complex objects, using the rules of interaction between different types of particles and a semi-permeable barrier of the potential function . This will allow obtaining crystals of any structure and size of a small amount of time. The maximum size of the crystal and builds speed depends on the physical characteristics of the computer.
Interaction particles during crystallization implemented using deterministic finite-state automation. Model particles are represented as complex spheres having the four radiuses: two for modeling the attraction, and two for modeling the second order neighbors repulsion . This will build crystals and molecules, the mutual arrangement of the atoms which is strictly regulated by physical characteristics. This task is necessary for the further simulation of the detonation of condensed explosives and surface combustion of dust of any kind. References: 1. Yarovskaya, B.M.
