波动方程的边界元解法

A Boundary Element Method of Solving on wave Eqvation

本文研究了求解二维域波动方程的边界元方法,给出了数值计算公式。通过对一个在Heaviside型力函数作用下的一维棒运动的计算,说明该数值方法是有效的,易在计算机上实现。

In this paper, the boundary element method of solving on two-dimentional wave equation is presented. The numerical calculation formula is gived. It is illustrated the method is efficient by computing one-dimentional rod motion under a Heaviside type forcing function.
