摘要
研究了数值求解双曲方程外问题的人工边界方法 .在圆形的人工边界上 ,得到了三类等价的完全无反射的人工边界条件 .
An artificial boundary numerical method for the exterior problems of the hyperbolic equation is considered. Three kinds of equivalent exact nonreflecting boundary conditions are derived on a circular artificial boundary. Numerical examples are presented and effectiveness of these artificial boundary conditions is demonstrated.
