The discrete element method is a numerical model capable of describing the mechanical behaviour of assemblies of discs and spheres. The method is based on the use of an explicit numerical scheme in which the interaction of the particles is monitored contact by contact and the motion of the particles modelled particle by particle. In this paper, a two-dimensional model for computing contacts and motions of granular particles of unform, inelasticity is presented. then, code is developed. Using force-displacement law and Newton's second law, we calculated contact force and motion of particle
And we reduce the calculation time by using linked list algorithm. The primary aim this paper is to approve computational result of continuum analysis which is on processing. The end of this paper, that code is compared with carl's code.
