MUSICis 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 or obtain a copy of the code here. Any questions should be directed to Brendan Griffen and then if that fails, Oliver Hahn.
