Abstract
Topology optimization methods are aimed to produce optimal design. These tools implement optimization algorithms that modify the distribution of some materials within a predefined design space without a priori ideas about the topology or the geometry of the best solution. In this paper, we study a specific tool that combines a genetic algorithm, a material distribution formalism based on Voronoi cells and a commercial FEM evaluation tool. In particular, we show, through a simple but representative study case, that it is possible to improve the performance of the topology optimization tool during the local research phase, i. e. the geometry and dimensional optimization phase for which the topology optimization methods are generally not well-suited.
