When run, the program simulates convection in 3d in much the same way

-same, just that we can now solve in parallel and with much higher
-resolution.

+<h3>Comparison of results with step-31</h3>
+
+Before we go to this testcase, however, let us show a few results from a
+slightly earlier version of this program that was solving exactly the
+testcase we used in step-31, just that we now solve it in parallel and with
+much higher resolution. We show these results mainly for comparison.
Here are two images that show this higher resolution if we choose a 3d
computation in <code>main()</code> and if we set
The computation was done on a subset of 50 processors of the Brazos
cluster at Texas A&M University.

For a much more modest run (less mesh refinement, only 35 time steps, but 50
processors as above), we get this as output:
