Application of a Moving Particle Semi-Implicit Numerical Wave Flume (MPS-NWF) to model design waves

We model regular and irregular design waves of interest in coastal ocean engineering, using a Numerical Wave Flume (NWF) based on Moving Particle Semi-Implicit (MPS) method. A key feature the is implementation new scheme for artificial viscosity, which original to Smoothed Hydrodynamics (SPH) method here formalised into MPS context. In addition, we complement NWF with wave generator dynamic boundary approach, absorption mechanism numerical damping zone. show that accurately calibrating terms has strong effect preventing particle clustering tensile instability, allows precise simulation phenomena engineering. The NWF-MPS validated available analytical experimental benchmarks, then applied reproduce violent impact vertical wall breakwater. Interestingly, novel requires much lower number particles obtain similar level accuracy as compared analogous SPH simulations run machines.
