Abstract

This paper considers a one-step modification of the predictor-correction method of adaptive artificial viscosity for solving gas dynamics equations. With the same order of accuracy in space and time, the modified method has the best characteristics in terms of performance of both sequential and distributed software implementation. The results of the calculations of several problems of gas dynamics and evaluation of the effectiveness of the developed software are presented, including an example of 3D modeling on a hybrid mesh containing more than 5 × 108 elements.
