MUSIC - multi-scale cosmological initial conditions
MUSIC is a computer program to generate nested grid initial conditions for
high-resolution "zoom" cosmological simulations. A detailed description
of the algorithms can be found in Hahn & Abel (2011). You can
download the user's guide here. Please consider joining the
user mailing list.
Current MUSIC key features are:
Supports output for RAMSES, ENZO, Gadget-2/3, ART, Pkdgrav/Gasoline
and NyX via pugins. New codes can be added.
Support for first (1LPT) and second order (2LPT) Lagrangian perturbation
theory, local Lagrangian approximation (LLA) for baryons with grid codes.
Pluggable transfer functions, currently CAMB, Eisenstein&Hu, BBKS, Warm
Dark Matter variants. Distinct baryon+CDM fields.
Minimum bounding ellipsoid high-res regions supported with most codes,
supports refinement mask generation for RAMSES.
Parallelized with OpenMP
Requires FFTW (v2 or v3), GSL (and HDF5 for output for some codes)
