报告摘要：

The development of a powerful software system based on the DSMC method was started at the Laboratory of Computational Aerodynamics (ITAM, Novosibirsk,Russia) at the end of the 1990s. This research resulted in the creation of the SMILE software system (Statistical Modeling In Low-Density Environment) based on Majorant Collisional Frequency Scheme of the DSMC method and capable of solving a very wide range of basic and applied problems of rarefied gas aerothermodynamics.

Our experience during the development of the SMILE software system clearlydemonstrates the fact that the greater the capabilities of the DSMC system are, the harder it is to modify the system by implementation of new collision models, methods and algorithms. The necessity for the creation of a DSMC software system based on the new-generation Object-Oriented Programming (OOP) approach became evident to us several years ago. The main goal of the present talk is to describe the basic ideology and demonstrate example applications of the SMILE++ parallel software system developed at ITAM. The SMILE++ is based on the OOP approach and is completely written in C++. SMILE++ is the descendant of SMILE system and incorporates most of its capabilities. At the same time, it has new capabilities and significant advantages offered by OOP.
