The Gadget-2 code is an SPH simulation code designed for cosmological simulations but can be used for a wide variety of astrophysical hydrodynamics simulations with self-gravity.
[Open source - Linux] "Hubble in a bottle!" is visualization software for N-body simulations, which can be run in parallel using MPI for visualizing very large simulation results. Simulation output must be in TIPSY format.
PHOEBE is an infrastructure for the numerical modeling and analysis of eclipsing binary stars, using a variety of models.
Cloudy is an extensive, well-established, large-scale spectral synthesis code designed to simulate fully physical conditions within an astronomical plasma and then predict the emitted spectrum. The web page contains links to papers published with cloudy, the most recent version of the software itself, and a discussion board.
CMBEASY is a C++ code with GUI for calculation of CMB power spectra and other density fluctuation evolution data for a given cosmology.
COSMOMC calculates a fast Markov Chain Monte-Carlo exploration of cosmological parameter space for an input set of constraints.
The FLASH code is a reacting hydrodynamics code with adaptive mesh refinement for general astrophysical hydrodynamics problems.
ZEUS is a venerable astrophysical hydrodynamics and MHD code that has been used to investigate a wide variety of astrophysical problems. The latest version includes gas hydrodynamics, ideal MHD, implicit flux-limited radiation diffusion (FLD), self gravity, and multispecies advection.
EZ (Evolve ZAMS) Stellar Evolution tracks the evolution of new (Zero-Age Main Sequence) stars throughout the bulk of their lives (until an event which EZ does not model occurs, such as a Helium Flash or core crystallization). The code is clean and well documented. Links include a web interface to the code.
DUSTY calculates the emerging spectrum of radiation from some source viewed after processing by a dusty region. The original radiation is scattered, absorbed and reemitted by the dust, and the emerging processed spectrum often provides the only available information about the embedded object. DUSTY can handle both planar and centrally-heated spherical density distributions. The number of independent input model parameters is minimized by fully implementing the scaling properties of the radiative transfer problem, and the spatial temperature profile is found from radiative equilibrium at every point in the dusty region. DUSTY has built in optical properties for the most common types of astronomical dust and comes with a library for many other grains.
