Polygonal Analysis and Polytree-based Adaptive Topology Optimization of Fluid-submerged Breakwater Interaction
2018
This research presents the application, for the first time, of polygonal finite element method (PFEM) and polytree-based adaptive topology optimization technique to simulate and optimize fluid-submerged breakwater interaction problems. They are integrated to investigate fluid-structure interaction (FSI) problems between fluid and submerged breakwater (SBW). Then an optimal shape of SBW is main goal of this study. In addition, SBW is one of the most interesting protected solution in coastal structures because its distinguished features, particularly, protecting the landside from the erosion without any loss of beach amenity and negative aesthetic influents for the recent decade instead of seawall, groins, breakwater, etc. And It is always subjected the fluid interaction. In this study, some numerical examples are presented to demonstrate the effectiveness of the proposed method. A finite element commercial package, ABAQUS software, is used to produce reference solutions for the numerical examples written in MATLAB.
