摘要
本文就波浪与结构物相互作用问题，提出了一个适用于高阶边界元应用的新的积分方程，并利用修改积分区域的方法得了适用于本积分方程的不规则频率消除方法。最后，通过数值计算对附加区域的选择。
The paper presents a novel integral equation for the discretization by higher order elements for the calculation of the wave diffraction and radiation from a 3 dimensional body. The irregular frequencies inherited in the integral equation for the bodies piercing the free surface are removed by the modified integral domain method.Numerical experiments have been carried out to find the best selection of the auxiliary domain and the discretization of meshes on it.
