摘要:The various setting of granular systems becomes an interesting and important thing to learn another granular-like system. Each system can represent different physical meaning. In this work, we perform two dimensions simulations of granular on the rigid wall. The varying initial velocities generate for each particle. We used two sets of the rigid wall, straight and inclined wall. The interaction of particle-particle and wall-particles used frictionless rigid body interaction. From the simulation result, observed that the small increment of a given velocity affected the reached maximum height particle as rapidly. The inclined wall indicates the less number of particles that pass through the wall. Future work can implement these results such as on granular energy damping.
