Abstract
The magnitude of impact force of highly nonlinear waves is very important in designing ocean structures. Using a numerical program based on N.S. equations, the impact forces of steep waves generated by a numerical wave maker can be studied. To validate numerical code, single frequency waves are generated and compared with analytic solution. The arbitrary steep waves are generated by the superposition of each wave and the results are compared with the experiment that shows an acceptable agreement. Wave loads acting on vertical cylinders are very complex and they can be simulated with multi-block grid method that can generate very complex geometries. Also the smooth wave profiles and the pressure contours across blocks can be obtained with multi-block grid system.. Copyright ? 2006 by The International Society of Offshore and Polar Engineers.
