ABSTRACT
Fast development of computational hardware and corresponding software made possible computer simulation of micro- and macroscopic properties of various condensed systems from classical nonideal liquids to solvated complexes of biological macromolecules. Physical interpretation of results of computer simulation suggests a knowledge of theoretical basics of computational methods of statistical physics and practical experience in the use of molecular dynamics (MD) and Monte Carlo (MC) methods in calculations of the structure and properties of disordered condensed systems. The general character of laws that govern properties of a macroscopic object is independent of the mechanics that describe the motion of its constituent particles. The main task of statistical physics is the calculation of the average values of various quantities (pressure, energy, magnetic moment, etc.) for macroscopic bodies in an equilibrium state and also fluctuations of the corresponding values. In the simplest systems (monoatomic ideal gases and solids), interaction between molecules can be neglected.
