To share the state-of-the-art numerical analysis capability on the interaction between extreme waves and a structure that is either fixed or with a forward speed, a comparative study was suggested at the ISOPE-2020 conference. Therefore, we have performed a computational fluid dynamics simulation for the wave interaction with a cylinder, where a focused wave is approaching the cylinder and then strong wave impact pressure occurs on the surface of the cylinder. The numerical simulations were performed using the commercial software STAR-CCM+. The measured stroke data of the wavemaker in the experiments were directly used as input to the inlet boundary of the numerical simulation, and movement of the cylinder was directly simulated in conjunction with an overset grid method. The numerical simulation results were directly compared with the experimental results. It was observed that the numerical simulation results are in fairly good agreement with overall physical phenomena and wave impact pressures from the experiments.
