Abstract:The numerical wave tank based on the potential theory simulates the wave progression and wave-structure interaction quickly, but it is based on the assumption of non-viscous. In reality, viscous effects are always considered at solid boundaries and wave-broken areas. For the viscous numerical wave basin based on solving the Navier-Stokes e-quation, however, it has the insufficient of large amount of calculation. Currently, the coupling method is used to sim-ulate wave progression to reduce the amount of calculation and enhance the efficiency. In the outer domain, multidi-rectional irregular waves are generated from potential theory, and in the inner domain, the Navier-Stokes equation is solved in combination the VOF method to track the free surface.
