Description
Summary:Since the electromagnetic-mechanical coupled analysis requires large computation time, the development of parallel processing techniques is inevitable. In this paper, the parallel computing technique with the combination of the domain decomposition method and the domain partitioned conjugate gradient method is proposed. The method to evaluate the parallel performance is presented and discussed for the coupled problem using a workstation cluster. This method is efficient for a large scale coupled problem of a magnetic fusion device component.
