Abstract
This work presents a study of a methodology for structural topological optimization of a fluid-structure coupled system with the objective of maximizing structural rigidity while its structural volume is gradually removed in order to obtain, for a fraction of volume, a structure with rigidity close of the original. The structure is part of a fluid-structural system and is subject to static external loads as well as loads imposed by the fluid. The problems addressed were discretized with an unstructured and irregular mesh and the topological optimization through the BEFSO (Bi-Directional Evolutionary Fluid-Structural Optimization), method which is an improvement of the BESO method. The results obtained demonstrate the robustness of the program developed since it is able to reproduce the cases of optimization presented in the literature, as well as to solve complex problems solved by conventional methods that normally use regular meshes or commercial software.
