摘要
在用数值方法求解微分方程时,把计算域网格结点分成各自的修正块,迭代求解过程中,在同一修正块内各个不同的网格点,其离散化变量取相同的修正量,从而加快高阶代数方程组的迭代收敛。
In the course of solving the differential equations with numerical method, mesh nodes in calculation region could be divided into each correction block separately. The discretization variables of different mesh node in same correction block are taken same correction quantity, it will accelerate the convergent speed of algebraic equations with high power.
