摘要
本文提出一种复变量半解析试函数,并将它应用于边界元法中,建立一种可对三维波动问题在频域进行分析的半解析边界元法。同一般有限元和边界元法相比,本文方法具有节省存贮空间和计算工作量等优点。
This paper presents a complex value trial function applied to boundary element method and establishes a semi-analytical boundary element method which can be used to calculate the three dimensional seismic wave problems in frequency domain. By this method, the computational effort and memory space are reduced considerably in comparison with the conventional finite element method and boundary element method.
