Understanding Dynamic Stability of Advanced Ships in Steep Waves by Direct Fully-Nonlinear Computations
Abstract
We develop an efficient O(N log N) quadratic-boundary-element method (QBEM) for thesimulation of the fully-nonlinear seakeeping problem by implementing the pre-corrected FastFourier Transform (pFFT) approach to reduce operation counts from O(N2~3) to O(N log N). Weapply fully-nonlinear simulations to quantify nonlinear hydrodynamic effects in the seakeepingproblem and investigate the physical nonlinear processes controlling the dynamic stability ofadvanced ships.
