MAC (marker and cell)method is applied to solve the N - S equation and continuity equation numerically. In order to simulate successive long-time wave generation of irregular waves and absorb the reflected waves from a structure, the source generation of waves is applied. A sponge layer for wave damping absorber combined with the Sommerfeld radiation is used to the open boundary.
