High-Frequency Electromagnetic Field Analysis by COCR Method Using Anatomical Human Body Models

The authors investigate a high-accuracy analysis technique for the electromagnetic field in a human body by using the parallel finite-element method. In the high-frequency electromagnetic field analysis with anatomical human models, speed-up of calculation is one of the most important topics. In this paper, we implement the code and evaluate the performance of two kinds of iterative method for the interface problem in the domain decomposition method (DDM) by numerical experiments using large-scale human body models. As the results, the conjugate orthogonal conjugate residual method is very effective as the interface solver in the DDM method for the high-frequency electromagnetic field analysis using the anatomical human model.
