DISCRETE ELEMENT METHOD (DEM)

 

DEM makes it possible to compute the moving behavior of a very large number of objects. These are called discrete elements or particles. Its uses range from modelling the ground conditions on other planets, to simulating processes of conveying granular media, to simulating production processes like frictionally grinding metal components, to just name a few of the many applications.

 

JDepending on each individual case, the particles may represent gravel pieces, plastic particles, metal parts or many other things. The shapes of the particles vary depending on the application, from simple geometric bodies like spheres or ellipsoids to geometries of real components which can be directly imported from a CAD program.

In discrete element simulations an immense number of contacts between the simulated particles have to be detected and and computed. This requires especially sophisticated algorithms to efficiently utilize the available processing power. For dealing with this problem most commercially available particle simulation programs support only an approximation of the real shapes of parts by spheres or other primitive geometric bodies. Even though this reduces computing time, it has a negative effect on the quality and value of the computed results.


The software Pasimodo®, in contrast, is capable of reproducing even large numbers of particles in shapes true to the originals by using its sophisticated contact algorithms. By importing CAD geometries it is easy to connect to typical work routines in design, research and development. Pasimodo® allows for DEM simulations with realistic geometry descriptions of particle quantities relevant to industry, done on commercially available workstations.
