| Abstract: |
We introduce a general-purpose framework for interconnecting
scientific simulation programs using a homogeneous, unified software
interface. Our framework is intrinsically parallel, and
conveniently separates all components in memory. It performs unit
conversion between different modules automatically and defines common data
structures to communicate across different codes. We use the framework
to simulate embedded star clusters. For this purpose we couple solvers
for gravitational
dynamics, stellar evolution and hydrodynamics to self consistently
resolve the dynamical evolution simultaneousy with the internal
nuclear evolution of the stars and the hydrodynamic response of the
gas. We find, in contrast to earlier studies, that the survival of
a young star cluster depends only weakly on the efficiency of star
formation. The main reason for this weak dependency is the
asymmetric expulsion of the embedding gas from the cluster. |
