Paper Abstract

The method of calculation of intensive charged beams on rectangular quasistructured grids is offered. The grids are constructed in two stages: first the computational domain is broken by a uniform rectangular macrogrid into subdomains, and then in each macrocell is constructed uniform rectangular locally-modified subgrid. The basis of this method is made with construction and the solving of system of the linear algebraic equations concerning values of an electric field potential in nodes of the grid covering a interface boundary of subdomains. The suggested method is direct as in it there are no iterations on subdomains. In the conclusion the basic properties of the considered approach are listed.
