In this paper, new global local iterative analysis method based on the overlaying mesh method is proposed. Pre-conditioned conjugate gradient algorithm using block global local pre-conditioner and several other pre-conditioner is compared and it was shown that block global local pre-conditioner gives much better iteration convergence, and overall better performance even compared with the multi-frontal direct method. The algorithm is also used by iterative analysis using general purpose commercial code.
