A SURFACE PANEL METHOD FOR THE CALCULATION OF ADDED MASS MATRICES FOR FINITE ELEMENT MODELS

A method for generating the added field fluid mass matrix for use in dynamic analyses of submerged structures is presented. This method uses a distribution of panel singularities in the form of sources or dipoles on the fluid/structure interface to represent the velocity potential in the fluid surrounding the structure. Based on the results of a variety of investigations of computational performance, convergence, and dynamic response of floating cylinders, ship hulls, and propeller blades, the surface panel method is shown to provide an effective alternative to the finite element added mass matrix system.
