In this paper a hybrid Eulerian Lagrangian solver based on the full-particle Particle-In-Cell (PIC) method is outlined. The solver is capable of simulating incompressible free-surface flows in domains with arbitrary, free-slip, solid boundaries. The flexibility of the approach allows for simulation of wetting and drying and pooling as well as wave breaking, splash-up over complex obstacles and the overtopping of coastal structures. The method has been validated for a wide variety of test cases and results are in good agreement with the numerical and experimental results of other researchers.
