摘要
本文提出数值求解二维、三维,Poisson方程的一类预示-校正型有限差分格式,以及相应的二阶、四阶和六阶格式精度的差分算子的一般构造。这类差分格式可以通过选择因子的不同取值控制和调节实际工程模型的计算误差,并可在粗糙差分网格中实现高精度的数值计算。
A kind of Predictor-Corrector difference Schemes for solving 2-D or 3-D Poisson equations numerically and the general constructions of difference operators with second-order, fourth-order, or sixth-order accuracy have been presented in this paper.The computational error of these difference schemes can be controled and moderated by the different values of the selected factor'. We can get more accurate numerical results of actual engineering models by using these optimum schemes in coarse difference meshes.
