    Abstract: 本文應用所謂的移動視窗的數值技巧,將全非線性時間域數值模型中因浮體進行任意運動時產生的波,傳遞至計算區域之外;避免因有限之計算區域而導致這些幅射波在傳遞至計算區域邊緣時,產生反射之現象;因而,在不受反射波的影響下,整個流場的情況及浮體在水面的運動情形和其所受之應力等得以確實的被模擬。本論文中並分析浮體進行長時間任意方向大範圍的運動情況時,應用本“移動視窗”的數值技巧下,使用一相對較小的計算區域,可達到長時間模擬大範圍運動之目的。
    An "moving window" numerical technique is used to propagate radiation waves caused by floating bodies through their arbitrary motions out of computational domains while fully nonlinear time domain numerical models can be properly applied to simulate the motions of floating bodies and the water-body interactions under no wave reflection condition. An idea of "moving window" numerical technique is also presented in this work. A relatively small computational domain can then be used to simulate arbitrary direction of motions of floating bodies for any duration of simulation time.
