Abstract :
This paper presents a simplified near-field preconditioner based on multi-level fast multipole algorithm (MLFMA). The preconditioner attains a low computation complexity, has no influence on memory requirement and is easy to be parallelized. It shows good performance in numerical experiments and is applied in solving a very large scale problem.
