MUSIC - multi-scale cosmological initial conditions
MUSIC is a computer program to generate nested grid initial conditions for high-resolution "zoom" cosmological simulations. 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)
