【Abstract】 A grid division method which minimizes the time-memory product of the precorrected-FFT method is presented in this paper, and how to apply the precorrected-FFT method to the analysis of wave-body interaction is described in detail. Numerical experiments indicate that a major reduction in computation time and memory is achieved, which makes it possible to solve large scale problems on personal computers with the precorrected-FFT method.更多还原
