Natural Convection in a Box

$

Hi, I'm trying to get that cats eye picture of natural convection in a box. My solution converges but I dont see any streamlines.

If someone can spot a mistake that I made, it would be helpful. I am trying to change the Rayleighs number in magnitudes of 10.

I had to delete the study to make the file size small enough but I ran the study as a time-dependant with a range of (0,1,180) along with a parametric sweep of the Rayleigh number (not in this model). Currently I only have it set to a Rayleigh number of 1000.

Any help would be appreciated. I attached my file and I am using 4.3b
