摘要
This paper deals with a 3D non-steady eddy current analysis of the rotating machine by the hierarchical domain decomposition method (HDDM). It is difficult to perform the parallel computing including the moving body without lowering the parallel efficiency. For example, the parallel computing of the rotating body by the parallel iterative method has been tried. However, its parallel efficiency is very low at approximately 60%. In this paper, in order to perform parallel computing including the moving bodies without lowering the parallel efficiency, the new algorithm is introduced to the HDDM. As a result, good scalability has been obtained by strong scaling of the rotating machine. Its parallel efficiency has been 93.3% with 96 nodes (1,536 cores) of Oakleaf-FX. © 2017 The Institute of Electrical Engineers of Japan.
