本文旨在應用三次多項式楔曲線(Cubic spline)近似法,在二維及三維之全非線性時間域數值模型中,用以模擬浮體在流場中作運動時,在不受因有限計算區域邊界而產生之反射波的影響下,得以確實預測其各項性能之數值分析技術並用以較實際地描述整個流場的情況及浮體在水面的運動情形。 A cubic spline method is applied to resolved the wave reflection problems while two dimensional and three dimensional fully nonlinear time domain numerical models are used to simulate the motions of arbitrary floating bodies, and the interactions between fluid and bodies. As computational domains for all the numerical models are finite, radiation waves will eventually reach the boundaries of computational domain. Reflection waves is then aroused. By eliminating reflection waves, the results of simulations can be correct and useful.
