摘要: 本文提出求解二维、三维Poisson方程的Dirichlet和Neumann两类边值问题的预示校正差分格式。它完整地包括求解区域的内结点格式、边界面结点格式、边界线结点格式和边界角结点格式。这种新的差分格式达到四阶精度,并可通过对选择因子的优越使计算误差达到最小。

Abstract: In this paper the predictor-corrector difference schemes of three-dimensional Poisson. equation with Dirichlet or/and Neumann boundary value problems are studied. It contains a complete set of schemes of the difference nodes which arc in inner region or in boundary planes, boundary lines and boundary corners. The new finite difference schemes can attain four-order accuracy with the least computational error by optimizing the selected factor.
