Huijsmans, R.H.M. Veldman, A.E.P. Borsboom, M.J.A. Wellens, P.R. Faculty Mechanical, Maritime and Materials Engineering Department Marine and Transport Technology Date 2011-09-28 Abstract In this paper the use of an absorbing boundary condition (ABC) is investigated for the numerical simulation of regular and irregular waves in three dimensional computational domains where Navier-Stokes equations describe the motion of the fluid. The numerical implementation of the ABC using a staggered grid arrangement is explained in detail. All of the numerical modifications are incorporated into the CFD simulation tool ComFLOW which employs a volume-of-fluid (VOF) method. Numerical examples are provided to demonstrate the performance of the ABC. The reflection character of the ABC is observed and the results of the computations are discussed and compared.
