Abstract: The 3-D Fast Multipole Method, a kind of gridless particle simulation method, is described and improved to obtain higher accuracy. A spherical particle with reduced dimensional motion model is presented. As examples, the spatial distribution of the potential in dust plasma and the instability produced by electrons streaming through ions are simulated. The results of simulations are in agreement with the theory.

Key words: FMM, gridless, particle simulation
