ON INCREASING COMPUTATIONAL EFFICIENCY IN HYDROELASTIC ANALYSIS OF VLFS

Two techniques are introduced in the three-dimensional hydroelasticity theory to increase the computational efficiency for the determination of the dynamic response of very large floating structures (VLFS). One technique is related to the convergence of the Green function and its derivatives, namely, the introduction of a criterion used to truncate the influence of the Green function and its derivatives. The other involves using an iterative sparse solver for the linear system of equations. The principle motivation behind the application of these two techniques stems from the fact that a source makes a very small contribution to the potential at a point "far away" from the source point. By employing these two techniques in the hydroelastic analysis of a VLFS, the CPU time and required storage are considerably reduced, and therefore it is now possible to analyze the dynamics of a VLFS as large as floating airport by using the 3-D panel method.
