Sumario:[EN] Engineering requires the minimization of the production and logistics costs. The time reduction is a critical factor for the costs reduction. Shape optimization is a process needed in order to achieve that goal, but with a time cost elevated, sometimes. In this MTh, some alternative optimization methods are presented which are intended to reduce calculation time. For this, a gradient based optimization algorithm will be used, since it is considered that they achieve the solution faster than the evolutionary algorithm. Great part of the calculation time is used in the calculation of the finite elements mesh. In order to quicken this process, a projection error method will be used. This method takes data from the previous iteration of the optimization process. All that may be achieved without losing result quality that would be achieved with conventional methods. Those methods assure the quality of the result whatever the calculation time. However, this MTh aims to optimize the calculation time. The objective of the MTh is to search a more effective method of doing shape optimization processes.
