7 The scaled boundary ﬁnite-element method (SBFEM) is a novel semi-analytical method 8 developed in the elasto-statics and elasto-dynamics areas that has the advantages of com- 9 bining the ﬁnite-element method with the boundary-element method. The SBFEM method 10 weakens the governing differential equation in the circumferential direction and solves the 11 weakened equation analytically in the radial direction. It has the inherent advantage of 12 solving the unbounded ﬂuid dynamic problem. In this paper, the boundary-value problem 13 composed of short-crested waves diffracted by a vertical circular cylinder is solved by 14 SBFEM. Only the cylinder boundary is discretized with curved surface ﬁnite-elements on 15 the circumference of the cylinder, while the radial differential equation is solved completely 16 analytically. The computation of the diffraction force based on the present SBFEM solu- 17 tion demonstrates a high accuracy achieved with a small number of surface ﬁnite-elements.
