有限差分方法 Finite Difference Method
有限差分方法(网格法)是最早使用的一种电磁场数
值计算方法。
边值问题
物理思想:场域离散。
(连续区域→网格和节点)
数学基础:差分原理。
(微商→差商)
线性代数方程组
§6-3 有限差分方法
作为数值计算方法,有限差分法将连续场域的问题变换
为离散系统的问题(连续场域划分为若干个细小的区域:网
格和节点)。也就是说通过离散化模型上各离散点的数值解
来逼近连续场域内的真实解。(The finite difference method (grid method) is the earliest use of an electromagnetic field the number of
Value method.
Boundary Value Problems
Physical idea: the field of discrete.
(Contiguous area → grid nodes)
Mathematical foundations: the difference principle.
(The Derivative → difference quotient)
Linear algebraic equations.
§ 6-3 Finite Difference Method
Numerical methods, finite difference method will transform the problem of the continuous field
For discrete systems (continuous field is divided into several small areas: network
Grid nodes). That is, the value of the discrete points in the discrete model solution
To approximate the true solution of the continuous field domain.)
