Abstract
This paper presents the recent development on the nonlinear directional wave generation process in a 3D Numerical Wave Tank (NWT). The NWT is based on a nonlinear model using the High-Order Spectral (HOS) method, which exhibits high level of accuracy as well as efficiency properties provided by a Fast Fourier Transform (FFT) solution. The wavemaker modeling appears to be a key point in the simulation and it is carefully detailed. Different levels of approximation of the wave generation (up to third-order in nonlinearity) are studied. The properties of the numerical scheme in terms of convergence, stability and accuracy are discussed. This NWT features all the characteristics of the real wave tank (directional wavemaker, absorbing zone, perfectly reflective side walls). Furthermore, several validation results and practical applications where numerical simulations are successfully compared to experiments on 2D and 3D wave fields are presented.
