CLASS
The CLASS [2] code is used to generate linear values for cosmological observables given specific cosmological parameters. This code can be used directly to produce a transfer function that is suitable as an input to the IC generation of PKDGRAV3, or it can be used in combination with CONCEPT for more advanced features.

CONCEPT
The CONCEPT code [3, 4] can be use to generate an HDF5 file with tabulated values from CLASS [2]. This file can be use as an input to PKDGRAV3 to provide the cosmology for initial conditions, and for the treatment of linear species.

CAMB
CAMB [6, 7] is another code that is commonly used to generate transfer function.

MUSIC
The MUSIC [5] code is a tool that can is used to generate initial conditions. It is particularly well suited to multi-scale (zoom) simulations.
