Abstract
A parallel software package designed for numerical simulation of continuum mechanics problems is presented. In order to illustrate the capabilities of the package, two problems on simulation of supersonic gas flows, around a descent space vehicle and in the vicinity of a micro nozzle, were chosen. A system of equations of quasi-gas dynamics was used as a mathematical model for the dynamics of gas. Inasmuch as radiation transfer in gas is taken into account in the first problem, the multigroup approach and diffusion approximation are employed to describe radiation processes. The numerical algorithm is based on explicit in time finite volume schemes using nonregular locally condensed grids of different types. Parallel implementation of numerical schemes was executed in the context of the MPI+OpenMP technology and optimized for computations performed by means of modern clusters with hybrid architecture.
