HIGHLY ACCURATE CALCULATION PROGRAM FOR POISSON EQUATION DIFFUSION EQUATION AND SIMILAR PARTIAL DIFFERENTIATION EQUATION USING SPATIAL DIFFERENTIAL COEFFICIENT IN NON-EQUAL INTERVAL GRATING

摘要

PROBLEM TO BE SOLVED: To accurately find out a Poisson equation, a diffusion equation and a similar partial differentiation equation by numerical calculation on non-equal interval gratings in one-dimensional, two-dimensional and three-dimensional spaces. ;SOLUTION: A numerical calculation program is formed by preparing a discrete equation using the subordinate variable of an equation and its spatial first order differential coefficient independently as subordinate variables on each grating point for a spatial second order differential term and a spatial third differential term.;COPYRIGHT: (C)2000,JPO
