| 摘 要： | 在数值解法中,普遍采用有限差分和有限单元法,两种程序所得结果都是一个待解的线性或非线性矩阵方程。超松弛迭代解法不仅算法语言简明,而且具有加速迭代收敛的功能。本文通过两维稳态导热有限单元法的实例分析,给出了确定超松弛因子最佳值的一种简单方法。

| Abstract: | Among the numerical methods.both of Finite-Difference and Finite-Element are used very popularly,Results of their programs are a set of linear equations or non-linear equations to be solved,The Over-Relaxation method is not only convenient and efficient method but also can speed up the convergency in the procedure of solution, In this paper,we provide a simple method to determine the optimum value of the Over-Relaxation factor and show an example through a Finite-Element programs of 2-dimensional steady state conduction problem. |
