Abstract: The methods of numerical simulation technology for wave surface and the velocity and acceleration of water particle were discussed. Meanwhile linear-filtering method was used to simulate wave surface and the velocity and acceleration ofwater particle in a fixed height. The results were compared with target spectrums (P-M spectrum).
Keywords: numerical simulation; harmonic wave superposition method; linear-filtering method
