Abstract :
3-D eddy current analyses are performed with parallelized ICCG solvers. In order to parallelize the ICCG solver, the present analysis uses the Block ICCG method (BICCG) and the Parallelized ICCG method with renumbering process (PICCG-RP) that is proposed by the authors. In the latter method, the global matrix is reordered to the matrix form appropriate to parallel processing. The parallel efficiencies of the solvers are evaluated. It is shown that the PICCG-RP can solve the eddy current problem more efficiently than the BICCG. We also propose the special renumbering process in the PICCG-RP for dual-processor machines
