%X This paper used the analogous molecular dynamics to simulate the developing process of 2-D aeolian sand saltation through parallel computation.In this model,we consider that the complex system is composed of the base mechanics processes, such as grain-bed impacting and the coupling between saltating grains and wind flow,etc.By parallel computation,we realized to calculate large system which include 72 000 particles.The preliminary result have shown that this model can simulate the essential properties of natural sand saltation,such as the profile of mass flux is agreement with experimental result well.
