Abstract

Novel approaches to the 3D optimal design of magnetic shields are presented, in which topology optimization is achieved with the aid of numerical magnetic field analysis. The numerical procedures are implemented by means of a genetic algorithm combined with hybrid finite element and boundary element methods. This results in an overall increase in the optimization speed with acceptable computational accuracy. Finally, we present numerical results that demonstrate the validity of the proposed approach.
