講座題目：FEM Simulation of Nonlinear Interactions of Water Waves and Floating Structures

主講人：吳國雄 英國倫敦大學教授

時間：1月10日（星期四）下午2:00-4:00

地點：3A103

講座簡介：Finite element method is one of the most widely used methods in science and engineering. The present talk will focus its applications in nonlinear interactions of water waves and floating bodies. The first part will cover the basic principle of the methods, including discretisation, shape function, weighted average, local matrix, global matrix, bandwidth etc. This will be followed by detailed examples of mesh generation and wave/body interaction problems, including structured mesh based (1) 2D floating body in force motion, (2) 2D resonance problems, (3) 2D solitary wave problem, (4) 3D sloshing problem, and unstructured mesh based (1) 2D wave maker problem, (2) 2D wave radiation by a wedge shaped body, (3) 3D large amplitude motion of cylinders and a floating FPSO, (4) 3D wave radiation problem by non-wall sided cylinder, (5) 3D second order wave diffraction by an array of cylinders, (6) 3D wave radiation problems by an arrange of cylinders.
