At this point we scaled the box to a physical size $S = 10$ pc, $H_2$ number density of 100 cm$^{-3}$ at mean molecular weight $\mu=2.33$, and a constant sound speed $c_s$ = 0.2 km s$^{-1}$. After turning off the forcing and turning on self gravity, we turned the simulation over the adaptive mesh refinement (AMR) code RAMSES \citep{2002A&A...385..337T}. The $1024^{3}$ base grid was maintained, along with 2 steps of adaptive refinement triggered when the local Jeans length became shorter than 4 grid cells \citep{1997ApJ...489L.179T}.   We integrated the box through $\sim1.25$ Myr of self gravitation evolution. Following \citet{2007ApJ...665..416K}'s definition of the turbulent turnover time in a box , $T_{turb} = S/(2 c_s \scriptstyle{M})$, we have $T_{turb} \sim 3$ Myr. The free-fall time $T_{ff} = [3\pi / (32 G \rho)]^{1/2}$, at the mean density of the simulation, is also roughly 3 Myr. In this paper we focus on denser moderately dense  gas, with $10^3 < n/{\rm cm}^{-3} < 10^{4.5}$; at these densities we have $0.2 \lesssim T T_{ff}  / \rm{Myr} \lesssim 1.0$. At 1.25 Myr the global structure of the simulated box is thus dominated by the turbulence, while the denser gas has had time to become organized by self gravity.
