2 Direct Simulation Monte Carlo of gas flows: Definitions Monte Carlo method is a generic numerical method for a variety of mathematical problems based on computer generation of random numbers. Direct simulation Monte Carlo (DSMC) method is the Monte Carlo method for simulation of dilute gas flows on molecular level, i.e. on the level of individual molecules. To date DSMC is the basic numerical method in the kinetic theory of gases and rarefied gas dynamics. Kinetic theory of gases is a part of statistical physics where the flow of gases are considered on a molecular level and described in terms of changes of probabilities of various states of gas molecules in space and in time.
