Краткое описание

Considered in this article is the realization of a dispersion relation preserving scheme on the locally refined grid and particularly various types of interpolation that conserve grid properties. Considered here are also original methods of locally crowded grid generation, the methods of solution interpolation on the boundaries of blocks with various grid steps, and the processing of boundary conditions.
