Density and velocity profiles at z = 0 for the smallest and largest boxes with the largest contrasts; see Table 2. In order to precisely test the background dynamics, we simulate an inhomogeneous universe without the standard primordial Gaussian perturbations (As ≈ 0). The inhomogeneous (Newtonian) N-body simulations perfectly follow the GR solution. Furthermore, thanks to the scale invariance, their rescaled evolution is the same. See Sect. 4.1 for more details.
