Method of Construction of Computational Grid for Three-Dimensional Simulation of Turbulent Atmosphere in the Fire Zone

摘要

A numerical method of constructing adaptive computational grids is described in Ω-dimensional space for solving the problems related to the simulation of spatially distributed parameters. This method permits the realization of adaptive construction of the computational grid domain in the simulation process. Here both a priori information and that obtained in the course of solution is considered as a criterion of adaptation for optimal selection of initial(basic)dimensions of elementary cells(orientation of elements of the introduced structure).
