【Abstract】 How to apply the precorrected-FFT method to the hydroelastic analysis of elastic floating body is described in this paper. Responses of large offshore structures are solved with this method. Numerical experiments indicate that a significant reduction in computation time and memory usage, which makes it possible to solve large scale problems on personal computers with the precorrected-FFT method, is achieved.更多还原
