Here, the skin friction coefficient will be plotted as a function of distance along the plate. First, click on Plots, then double click on XY Plot, as shown below. In the Solution XY Plot menu deselect Write to File, select Position on X Axis, set X to 1 and set Y to 0. Then, set the box located underneath Y Axis Function to Wall Fluxes and set the box below to Skin Friction Coefficient. Next, select plate under Surfaces and deselect any other geometry features. At this point your Solution XY Plot menu should look the same as the following image.

It is of interest to compare the numerical skin friction coefficient profile to the skin friction coefficient profile obtained from the Blasius solution. In order to plot the theoretical results, first click here to download the necessary file. Save the file to your working directory. Next, go to the Solution XY Plot menu and click Load File... and select the file that you just downloaded, BlasiusSkin.xy. Lastly, click Plot in the Solution XY Plot menu. You should then obtain the following figure.
