Now, let's take a look at the coefficient of skin friction. This time, load the cf.xy file to compare against the plot. This is the coefficient of skin friction plot:

Once again, we can see that due to the fine degree of each mesh, there isn't much difference between the two plots. Save this plot as cf2.xy. Now, study the velocity of the outlet by plotting and comparing to the graph in profile.xy.

Once again, the finer mesh in this case doesn't offer much more precision than the coarser mesh. Save this plot as profile2.xy. Now let's take a look at the YPlus plot.

As we can see, there is a significant increase in the accuracy of the plot from the finer mesh. Save this plot as yplus2.xy.
