Abstract
A parallel program complex for 3D viscous gas flow simulation is presented. This complex is based on explicit finite difference schemes, which are constructed as an approximation of conservation laws (control volume method), and oriented towards use of locally refined grids. A special algorithm and utility for nested grid partitioning was created. The principles of program construction permits one to introduce new types of boundary conditions and change the finite difference scheme as well as the governing equation system. Introducing new face types and writing new subroutines for flux calculations may reach it. The scalability of the program complex was investigated on different subsonic and supersonic problems. The calculations were made on different types of cluster computer systems. The parallelization efficiency was more than 90% for 40 processors and more than 60% for 600 processors.
