Mechanism of the oscillation instability is then illuminated in frequency domain by amplification at the artificial boundary and multi-reflection of wave motion in a finite discrete model.
根据波在人工边界的放大效应和在有限离散模型中多次反射的概念在频域内阐明了这一常见的振荡失稳的机制。

In this paper, the motion of buoy is obtained numerically using a high-order boundary element method in the time domain based on the linear 3-d potential theory.
本文应用高阶边界元的数值方法,基于三维线性势流理论在时域内实现了浮筒运动响应的数值模拟。
