Figure \[fig:snrevol\] we show the density for four snapshots of the evolution for one simulation. For this case we use a value for the WL parameter $C = 10$, ratio of mass in clouds to that in the intercloud medium. Given the definition of $C$, the volume filling factor of clouds is $$f = \frac{C}{\chi + C}$$ where $\chi$ is the ratio of the cloud density to the intercloud density. With our assumption that $\chi = 100$, for the $C = 10$ case, $f = 0.091$. For our 2D cylindrically symmetric runs, the clouds are really toroids. However, for these cases the area filling factor, that is the fraction of the $r-z$ plane filled with clouds, is quite close to the volume filling factor of the toroidal clouds. If the clouds are evenly distributed in cylindrical radial distance this will always be the case. We have explored a range of $C$ values ranging from 3 to 30. We take 10 as our standard case for much of the discussion in this paper. Figure \[fig:slice3D\] shows the density for a slice through one of our 3D runs. That run also had $C = 10$. Note the similar area filling factor for
