N2 - A new hierarchical cell algorithm in combination with multi-pole expansions of the long-range forces in a Molecular Dynamics environment is presented. The model, based on the linked cell algorithm, is applied to ring-shaped particle aggregates. For such systems the relevance of the interplay of both short-ranged and long-ranged interactions will be the topic. We will present the time evolution of astrophysical objects with dissipation and self-gravitation, like e.g. massive planetary rings or dust disks orbiting around central objects. Of special interest is the cluster and structure formation of such particle systems in the presence of dissipation and self-gravity.
