As demonstrated in experiments, highly nonlinear reactions exist in the``Chinese Fish Basin'', which finally lead tothe surface discontinuity. It is difficult to deal with such problems innumerical simulation.In this paper, Molecular Dynamics Method is employed to simulatethree-dimensional granular flow in Chinese Fish Basin.we consider particles in the container from the viewpoint ofdiscretization, without the requirement of continuous media. When thenumber of particles in the simulation is large enough, the behaviors ofgranular flow are statistically equivalent to those of the continuous media.We first develop a parallel program based on message passinginterface(MPI), which can be used to simulate large scale granularflow. Interesting phenomena in the ``Chinese Fish Basin'' aredemonstrated with our simulation results. As a result of the excitationfrom outside, energy from the boundary spreads to theinterior of the basin in the form of wave, and dissipates quickly. Andparticles spout upward near the excited points, which is in consistentto the water spouting in the real Fish Basin.
