Smoothed Particle Hydrodynamics (SPH) method for modelling 2-dimensional free surface hydrodynamics

The main goal of the current research is to implement Smoothed Particle Hydrodynamics (SPH) for the prediction of wave-induced motions and loads within the framework of 3D modelling. In this paper, the focus is twofold. First, implementation of possible additional terms to the standard incompressibl...
