Add to ORKGIn this paper, a calculation method for wave impact problems is presented. This method is based on the Navier-Stokes equations and uses an improved volume-of-fluid (VOF) method for the displacement of the free surface. Results are shown for a dambreak simulation for which experimental results are available for comparison. Also drop tests have been simulated with wedges and circular cylinders. The results are very promising for the further development of the method
