Abstract
The two- and three-layer versions of a symmetric implicit difference scheme on distributed nets in the case of the one-dimensional equation of gas dynamics in the Euler form are considered. The approximate viscosity of the scheme is investigated by the method of differential approximation. The change in the approximation properties of the scheme when a mobile net is employed is analyzed. The results of a numerical experiment are presented.
