Overview

We use the multi-scale cosmological initial conditions creator MUSIC. 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 or obtain a copy of the code . Any questions should be directed to and then if that fails, .

Parameters

These are the parameter files which were used to generate the initial conditions for the Caterpillar project. We adopt the raw Planck (2013) cosmology and do not use 2nd order Lagrangian perturbation theory. The contains all the information required to understand the following parameter files. Within each simulation directory, there is a file named OUTPUTmusic which gives the log of the construction of the initial conditions.
