Master or Diploma Thesis "Improvement of the optimization algorithm for FEM simulations" (IPMS-2019-013)
The electrostatic MEMS-actuators developed by Fraunhofer IPMS („Nano e-drive“) have complex geometries, that can be defined through different parameters. To maximize desired actuator characteristics like force or deflection, these have to be chosen ideally. This is achieved by utilizing the CMA-ES optimization algorithm.
The aim of this work is, to adapt the above-mentioned algorithm to be more time efficient when doing consecutive optimizations with similar sets of parameters. Therefor results of finished optimization runs have to be used to predict the results of follow-up runs to accelerate them. Finally this has to be implemented in a user friendly process that can even be utilized by untrained users.
