FINITE ELEMENT SOLUTION FOR ADDED MASS AND DAMPING

Two-dimensional cylinders undergo small-amplitude forced sinusoidal motion at the free surface of an ideal fluid. Using a finite element representation of the fluid region, discretized equations of motion are presented. A radiation boundary condition allows simulation of regions of infinite width. For heaving motion, computer solutions are obtained for three different hull forms. Results are compared with published analytic solutions for regions of finite depth and infinite depth. It is shown that the finite element method can give satisfactory solutions for these problem. The method is especially useful for fluid regions of non-uniform depth.
