Utilization of parallel computing for mathematical modeling of high-enthalpy flows

Abstract

Abstract The complexity of problems in gas dynamics is increasing from year to year, which makes sequential computational codes more and more inadequate and brings the importance of creating their parallel implementations. The problem of building the parallel implementations is not simple, especially in case of parallelization of the existing sequential codes. In this paper we present a method of simulation of high-enthalpy flows and describe the peculiarities of its parallel implementation utilizing PETSc library, which gives a wide variety of tools to simplify creation of parallel codes. The results for calculation of OREX reentry module as well as analysis of scalability of the parallel code implementation are given.
