Based on the secondary development in Fluent

the study built a 2D numerical wave tank by the method of momentum source. Firstly

the established wave tank was used to simulate the resonance phenomenon between the waves and multi-floating bodies

and the numerical results were in good agreement with the experimental data. The results showed that the horizontal force acting on the last body was the largest. Subsequently

the influences of draft on resonance phenomenon were analyzed

indicating that the horizontal force acting on each body was

on the whole

correlated with its draft while the relation between vertical force and draft varied with the body. In the end

the influence of the addition of third body on resonance phenomenon in the gap was discussed

showing that resonance frequency would move to lower and the second resonance frequency would probably appear when the third body was added into the floating system.
