Abstract
An extension from 2D to 3D of the fully-nonlinear numerical wave tank (NWT) used by Hanssen et al. ispresented. Potential-flow theory is assumed, and the high-order harmonic polynomial cell (HPC) field methodproposed by Shao and Faltinsen is used to solve the governing Laplace equation for the velocity potential ?numerically. The present work deals with an immersed boundary method without and with the use of an octreetechnique for local grid refinement near the air-water interface, and examines only wave propagation; dealing withwave-body interactions is planned as a future development.File in questo prodotto:
