Rigid‑body analysis of a beveled shape structure in regular waves using the weakly compressible smoothed particle hydrodynamics (WCSPH) method

In many cases of wave structure interactions, three-dimensional models are used to demonstrate real-life complex environments in large domain scales. In the seakeeping context, predicting the motion responses in the interaction of a long body resembling a ship structure with regular waves is crucia...
