摘要
En 中文
A three-dimensional N-body tree code to model collisional processes in plasmas is described. The technique, based on the Barnes-Hut N log N algorithm, is shown to be more efficient than the usual O(N2) particle-particle method and competitive with the O(N) fast multipole method, within a ''window'' of N = 10(3)-10(5) particles. Examples are given which demonstrate the code's potential for first-principles simulation of a diverse range of systems; from collisionless (GAMMA --> 0) to strongly-coupled plasmas with GAMMA much greater than 1.
