METHOD FOR SIMULATING A CHARACTERISTIC OF A PHYSICAL SYSTEM

摘要

A method is provided for simulating at least one characteristic of a physica l system. The physical sytem is discretized into a plurality of volumetric cells (201-215) having boundaries therebetween. An initial estimate of state variables is assigned for each cell. For each cell, linear equations are constructed relating its state variables to the state variables of cells adjacent to it. A transportability value is associated with each boundary and the boundaries are ranked corresponding to descending transportability values. The boundary rankings are used to construct topologically one-dimensional strings of cells (50, 51). A matrix equation for each string is constructed by assembling the linear equations associated with the cells for each string. Improved estimates of t he state variables of the cells are determined by solving the matrix equations. These state variables are then used to simulate at least o ne characteristic of the physical system.
