作者利用并行有限元法研究了人体电磁场的高精度分析技术。在人体解剖模型的高频电磁场分析中，计算加速是最重要的课题之一。本文通过大规模人体模型的数值实验，实现了代码实现，并评估了域分解方法（DDM）中界面问题的两种迭代方法的性能。结果表明，共轭正交共轭残差法作为使用解剖人体模型进行高频电磁场分析的 DDM 方法中的界面求解器非常有效。
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.
