Abstract: The parallel program complex for numerical modeling of the continuous media mechanics problems is represented. For demonstration of complex possibilities two problems are chosen: modeling of supersonic gas flow around space vehicle and near to a micro nozzle. As mathematical model of gas dynamics the quasigasdynamic equation system is used. For the first problem we take into account radiation transfer. To describe of radiation processes the multigroup approach and diffusion approximation are implemented. The numerical algorithm is based on explicit on time finite volume schemes. For calculations irregular locally condensed grids of various types are used. Parallel realization of the numerical schemes is executed within MPI+OpenMP technology and optimized for calculations on modern clusters with hybrid architecture.

Keywords: simulation of aerodynamics problems, high performance computer systems, parallel program packages.
