Abstract
The method of adaptive artificial viscosity (AAV) [1, 2] as applied to gas dynamics problems in cylindrical, spherical, and Cartesian coordinates is considered in the paper. A new way of choosing artificial viscosity, resulting in the weak diffusion of shock waves (into three intervals), and accurate smoothing of oscillations of solutions having a grid nature is suggested. The calculation results are presented.
