摘要
精确而又快速地求取时域Green函数及其空间导数是应用时域法求解船舶水动力学问题的关键。本文探讨了这些函数的算法,导出了相应的简化算式,并提出了一种为克服这些函数插值的困难所能采用的方法。验算表明,该算法是有效的。
Fast evaluation of time-domain free surface Green Functions with sufficient accuracy is the key to the employing of time-domain approach in solving hydrodynamic problems. In this paper, an algorithm for these functions is developed, and the relevent formulae are deduced for the approximation. A feasible technique is put forth to tackle the difficulty in the interpolation of the functions. The tabulated approach is shown to be efficient.
