For coastal engineering problems, wave modeling is required for various spatial scales. The development of high-resolution Computational Fluid Dynamics (CFD) based numerical wave tanks (NWT) has gained a lot of attention. The Navier-Stokes equations are solved together with a two-phase interface capturing algorithm. The interface capturing treatment of the free water surface is performed on fixed grids, allowing for the simulation of complex wave phenomena such as breaking waves. In the current paper, the three-dimensional open-source hydrodynamics model REEF3D is extended from a CFD-based NWT to a nonhydrostatic wave model, suitable for economic large scale computation of waves.
