PackGeo generates dense random sphere packings, where the sphere diameter distribution is variable.
In PackGeo two different algorithms are used:
The spheres, which have a repulsive force between each other, are packed denser and denser (Figure 1). High packing densities are achieved. The packing density, which naturally has an upper limit, is variable. This algorithm can be used, e.g. to determine the maximal packing density for a given sphere diameter distribution.
The spheres fall down under the influence of gravity and form a dense sphere-pile (Figure 2). The packing density is a result of this process and hence not variable. This algorithm is fast and a large number of spheres can be packed.
