In this article, domain decomposition is combined with a subdomain pre-processing technique to model wireless power transfer setups, in which the sending and receiving coils move relative to each other. Domain decomposition is used to decouple the problem into two subdomains, which contain the coils, and a main domain, which contains the medium and the relative placement. The subdomains are dictated by the coil design, and only the main domain must be modified to vary the relative placement of the coils. Linear mappings that describe the behavior of the subdomains in order to reduce the amount of degrees of freedom are computed. This approach greatly reduces the overall computational complexity of the repeated simulation.
