**DESCRIPTION** (simulation paper:

arxiv:1711.10524):

MassiveNuS (Cosmological Massive Neutrino Simulations) include 100 massive neutrino models + 1 massless model with three varying parameters (

parameter file):

(1) neutrino mass sum M_nu (ranging from 0 to 0.6 eV, assuming normal hierarchy)

(2) matter density Omega_m

(3) primordial power spectrum amplitude A_s (sigma_8 is a derived parameter)

The simulations correctly capture the background expansion as neutrinos turn from relativistic to non-relativistic, as well as the growth of neutrino clustering in response to the nonlinear matter growth.
