The gravitational interaction between N-body (star clusters) and hydrodynamic (ISM) codes in disk galaxy simulations

Abstract

In summary, development and testing of a combined hydrodynamic and N-body code are now underway. The work here at Maine is necessarily on a small grid because of the limitations of the computers available. It is already clear that physically meaningful results will require much finer grids, more N-body particles (250,000 vs 5,000 now), faster throughput, and better output devices. We will be performing this upgrade on the Cray computer at Nasa-Ames in the near future.
