Abstract:

Considering the efficiency of calculation, according to the characteristics of the real discrete particle systems, the cellular automata model is designed and built, and an example in a threedimensional spiral space is given and analyzed. Examples show that the method can be run in threedimensional complex space, and the cellular automata can qualitatively reflect the phenomena of the contact and friction between particles. The method can be used to display the evolution of threedimensional discrete particle system dynamically, and the computational performance of CA is highly over one of the discrete element method.
