Abstract: In this paper, a numerical wave tank is developed based on High Order Spectral (HOS) method, considering the wave-maker boundary. Comparison of the numerical results with the experimental data shows that the model can simulate the wave generation and propagation, even for the freak wave. Using this model, the 2D irregular wave trains with single peak spectrum and the bimodal spectrum are simulated for a long time. Freak waves are observed in the numerically simulated random wave trains. As a result of the existence of high frequency energy, the probability of the freak wave generation in the bimodal spectrum is greater than that of the single peak spectrum, which provides a basis for further research of freak waves.
