AMUSE (Astrophisical MUltipurpose Software Environment) started as small project to couple a number of gravitation dynamics and stellar evolution codes. However, with a dedicated team of developers and a large international user base, it has grown over the past 10 years to become a great research tool. The consistent python interface makes it possible set up fast high quality simulations in a matter of hours (or as a classroom experiment). As creator Simon Portegies Zwart says: "Our aim is to provide a software framework for astrophysical simulations, in which existing codes from different domains, such as stellar dynamics, stellar evolution, hydrodynamics and radiative transfer can be easily coupled."
