Besides, such complex geometries can nowadays be obtained in reality with the constant improvement of additive manufacturing. However, the capacity to obtain a very competitive design, balanced with a relative short computational time, is an important challenge. Therefore, the aim of this work is to test different topology optimization software and compare their performance, along with the Swan open-source GitHub repository. Different benchmark problems are analyzed, as well as a final example consisting of the design of a bicycle frame. In general, the results have shown that topology optimization commercial software are a useful and functional technology. Nevertheless, it still has a lot of room for improvement, given that certain geometries and restrictions can cause problems that directly affect the integrity of the part. Regarding the Swan case,it has also a great room for improvement in some aspects, such as the time, but, despite of using a significant amount of time for their simulations, it was proved that is a very robust software. 2024-02-05 Bachelor thesis http://creativecommons.org/licenses/by-nc-nd/4.0/ Open Access Attribution-NonCommercial-NoDerivs 4.0 International Universitat Politècnica de Catalunya
