  [FRS] This paper presents the method of fundamental solution for water wave-structure interaction analysis with multiple cylinders. The method of fundamental solution (MFS) is strongform of boundary meshless collocation method. Its numerical solution is approximated by a linear combination of fundamental solutions in terms of sources, which are placed on the fictitious boundary outside the domain of the problem to avoid the singularities of fundamental solutions at origin. In this study, two types of ocean engineering structures, circular and elliptical cylinders are considered. Numerical results show the efficiency and accuracy of the method in comparison with the singular boundary method (SBM). The near trapped mode phenomenon of four and sixteen hard cylinder structures are revisited.
