# 基于MATLAB与COMSOL联合仿真的电磁优化设计 Optimum Electromagnetism Design Based on Co-Simulation of MATLAB and COMSOL

Abstract: The genetic algorithm (GA) is a type of intelligent optimization algorithm that learns from biological genet- ics and natural selection mechanism. There are varieties of mature genetic operators integrated in the genetic algorithm toolbox of the MATLAB, and we can complete variety of optimization problems easily through the toolbox. COMSOL Multiphysics is a large-scale numerical simulation software. Efficient computing performance and outstanding multi- field direct coupling capabilities ensure highly accurate numerical simulation of arbitrary multi-physics fields. In order to make the genetic algorithm apply to optimum electromagnetism design, we studied the method of calling COMSOL in MATLAB, and completed the data transfer between MATLAB and COMSOL. Then we successfully used this opti- mum design method on a Helmholtz coil, and thus verified the feasibility of this method.
