Title: Virtual Source Method Simulation of Progressive Water Waves

Abstract: The virtual source method (VSM) has been developed to simulate water waves based upon the solution of Laplace’s equation for the velocity potential integral equations with full nonlinear surface conditions. The basis of the method is the use of specific Green’s functions for a rectangular ‘virtual domain’ which is an extension of the physical domain. The solution variables are frequency components of the velocity potential at the upper virtual boundary and these are found by specifying appropriate conditions on the physical boundaries. This talk will present the results of the VSM simulations to generate nonlinear progressive waves in a numerical wave tank. The VSM results are compared with those from both second order Stokes theory and from a boundary element method (BEM).
