Advanced Applications of an Automated Generative Tool for MEMS Design Based on COMSOL Multiphysics

This work presents a different use of COMSOL, not only as a simulation platform for engineering tasks, but also as an integrated component of a computational AI tool framework used to automate designs creation. CNS-Burst is a computational synthesis method used to create solutions to an assigned design task. This search method, iteratively applied, finds design alternatives and represents them as geometrical objects. In this context, COMSOL is integrated in the method and used to evaluate the performance of the design solutions found. Geometrical objects are transformed in COMSOL objects for analysis and simulations. In this work we have looked at case studies for which industry is interested in finding innovative solutions in a short timeframe. We also looked at a design field that could be accurately analysed using COMSOL. The design field here examined are MEMS. In particular, the case study chosen are sandwich resonators. This paper can be of interest not only to see how COMSOL has been used in this innovative academic project, but also to explore how MEMS design innovation is investigated.
