【 摘 要 】
A numerical model for the computation of the nonlinear interaction of water waves and floating large-volume bodies is described. The model works in the time domain and is based on the boundary element method (BEM) with internal generation of the incident waves and absorption of all outgoing waves (internally generated as well as reflected). This procedure makes it possible to simulate long time series of nonlinear wave forces even in case of irregular waves. Drift forces are extracted from the time series by filtering. Steady and slowly varying drift forces are computed in 2D and first order wave forces are computed in 3D.
