Abstract

An algorithm for construction of dynamically adaptive 3D grids is described. Conditions for determining the time step and restrictions on grid transformations are given for the case where Rodionov's UNO scheme is used for solving a system of the Euler equations on a moving curvilinear grid. The efficiency of using the dynamically adaptive grids is demonstrated by solving the problem on gas-dynamics consequences of a cosmic body explosion in the Earth atmosphere.
