A numerical simulation of extreme waves and wave-structure interaction is studied using OpenFOAM.
A new wave boundary condition based on a focused wave group with second order Stokes wave theory is integrated in waves2Foam within OpenFOAM.
Results agree well with physical experiments, including the surface elevation and the pressure at the front of the structure.
The OpenFOAM model is well placed for extension to many coastal engineering applications to simulate a wide range of nonlinear wave conditions.
