Method of adaptive artificial viscosity for the equations of gas dynamics on triangular and tetrahedral grids

In the papers [1–7] the adaptive artificial viscosity method (АAV) for solution of gas dynamics equations was proposed. In this paper this method is extended to the case of triangular grids for 2D case in $x$, $y$ and $r$, $z$ variables and tetrahedral grids for 3D in the Cartesian ones. Results of test computations are discussed.
