Description

I describe the approach for modelling the evolution of stellar systems with particle-based models using basis-set and multipole potential expansions. Several variants of this approach span the range between the self-consistent field method of Hernquist&Ostriker and the Lagrange point stripping method for stream generation, with different tradeoffs in complexity and realism. I discuss practical aspects of this technique, focusing on two applications: (1) tidally disrupting satellites, and (2) the Magellanic system.
