FEM Solution of 3‐D Wave Interference Problems
Publication: Journal of Waterway, Port, Coastal, and Ocean Engineering
Volume 111, Issue 4
Abstract
A numerical procedure for predicting wave diffraction, wave radiation, and body responses of multiple 3‐D bodies of arbitrary shape is described. Viscous effects are neglected, and the hydrodynamic pressure forces are assumed to be inertially dominated. Within the limits of linear wave theory, the boundary value problems are solved numerically by the finite element method (FEM) using a radiation boundary damper approach. Both permeable boundary dampers and a fictitious bottom boundary element are included in the finite element algorithm in order to treat both permeable boundary problems and deep water wave problems. Numerical results are presented for a variety of structures to illustrate the following features: fictitious bottom boundary, multiple‐structure wave interference, and permeable boundary.
