Method of Adaptive Artificial Viscosity for Gas Dynamics Equations on Triangular and Tetrahedral Grids

摘要

In studies [1–7] a method of adaptive artificial viscosity (AAV) was proposed for the solution of gas dynamics equations. In this paper, this method is extended to the case of triangular grids for two-dimensional (2D) equations in the variables x, y, and r, z, and of tetrahedral grids for equations in Cartesian variables x, y, and z. The calculation results for the test problems are presented.
