Abstract
The authors have investigated a high-accuracy analysis for the electromagnetic field of anatomical human body models using the parallel finite element method. In the full-wave electromagnetic field analysis by the parallel finite element analysis with anatomical human models, efficient conversion from voxels to finite element meshes and speed-up of an analysis become important topics. In this paper, we propose parallel mesh generation method with mesh smoothing, and show to be able to generate large-scale mesh very effective. Then, we evaluated the performance of two kinds of iterative method by numerical experiments using large-scale human body model. As the results, the COCR method is very useful as the interface solver in the DDM for high-frequency electromagnetic field analysis using anatomical human model.
