Computer simulation of granular materials

Mohammad Saadatfar has reviewed a range of granular material theories and numerical simulation techniques. He has made an effort to find the way these techniques can be used to simulate granular materials simulated on computers. He states that granular packing can be simulated, by creating all of the system's potential states through Monte Carlo (MC) simulation, or by calculating that forces that each particle experiences in the packing, and integrating the equation of motion to obtain the new positions of the particle. The new positions of particle can be obtained through the molecular dynamics (MD) simulation approach. A number of major sequential, or concurrent simulation techniques are also used in simulating granular materials. The system has a small number of fixed particles, as its starting configuration in sequential methods. The entire set of particles is present from initial stages of the simulation in concurrent methods.
