Numerical analysis of onshore structure and wave-dissipating blocks against water waves by 2D and 3D coupled simulation based on multi-resolution particle method

Abstract In this study, we developed a tsunami simulator using a multi-resolution particle method to address complex phenomena such as wave pressure on onshore structures and the stability of wave-dissipating blocks. The multi-resolution method used is the overlapping particle technique (OPT) for multi-resolution simulation of particle methods. In addition, the simulator was enhanced by the introduction of the energy-tracking impulse method, which allows rigid body contact and friction calculations. The OPT-based simulator has been validated in wave and onshore structure impingement simulation and stability analysis of wave-dissipating blocks.
