Multilevel-Multigrid simulation techniques

摘要

A method for generating a multigrid domain for use in a simulation of wave propagation in a physical system, the method comprisinggenerating a nested arrangement of embedded grids forming the multigrid domain by generating an initial grid having a selected time step and cell size, which initial grid is to be the finest grid in the multigrid domain, and iteratively performing the step of generating a coarser grid in which a grid generated in a previous iteration is to be embedded, starting with the initial grid, and ending with the generation of a base grid.
