The paper shows a numerical application developed for the PC that uses the high computing capabilities of the modern graphical processors to employ the discrete element method (DEM) in the modeling of the granular media behavior subjected to external and internal actions. The discrete element method is usually a suitable way to simulate the behavior of media and dynamic phenomena that have a discrete nature, such as soils liquefaction, erosion, or the propagation of instability through soil or snow masses. DEM is more precise for these types of phenomena due to the fact that a pseudo-continuous approach doesn't succeed to properly model them after the state of equilibrium has been lost. The paper shows the basic principles of DEM, an iterative computation example using computational software, as well as the developed software application that uses an existing solver to handle up to about 5000 particles in real time computation.
