Abstract: Advances in computational power have permitted the use of Lagrangian particle methods to model fluids, particularly separated flows and free surface flows with splashing. Here we present a smoothed particle hydrodynamics (SPH) approach to a numerical wave tank, capable of studying several types of waves impinging on structures and walls.
