Abstract
We present an accurate three-dimensional (3D) Numerical Wave Tank (NWT) solving the full equations in the potential flow formulation. The NWT is able to simulate wave propagation up to overturning over an arbitrary bottom topography. The model is based on a high-order 3D Boundary Element Method (BEM) with the Mixed Eulerian-Lagrangian (MEL) approach. The spatial discretization is third-order and ensures continuity of the inter-element slopes. Waves can be generated in the tank by wavemakers or they can be directly specified on the free surface. A node regridding can be applied at any time step over selected areas of the free surface. Results are presented for the computation of overturning waves over a ridge and their kinematics.
