| Abstract |
Offshore/marine renewable energy is witnessing a rapid development nowadays around the world. This calls for a powerful numerical tool, ideally open-source packaged, to accelerate relevant research. T...he present paper introduces a numerical open-source package that has been recently developed in Research Institute for Applied Mechanics, Kyushu University. The software package aims to compute Green’s function of finite water depth encountered in wave-structure interaction. As an essential part of the potential flow theory, computation of free-surface Green’s function becomes extremely troublesome and demanding. In the present package, a brand new algorithm is developed basing on a sophisticated region-decomposition strategy. Benchmarks are used for validation of the package, proving the balance of efficiency and accuracy. Furthermore, to show its application, a real-scale floating offshore wind turbine platform is computed as well for its behavior in real sea conditions.show more
