Parallel processing of 3-D eddy current analysis with moving conductor using parallelized ICCG solver with renumbering process

Abstract

A new parallelized ICCG scheme is applied to a finite edge element analysis of a 3-D eddy current problem with a moving conductor. In the new method, the global matrix is automatically reordered to the matrix form appropriate to parallel processing. The method requires no particular pre-processing step. It is shown that the newly proposed method has a better parallel efficiency than the Block ICCG method because of a higher preconditioning effect.
