To measure the shock angle, we first need to create a line that we can plot the coefficient of pressure over. In the Solution XY Plot window, click New Surface > Line/Rake. We will arbitrarily use the line, y = 0.35. Set the start point of the line as (0,0.35), and the end point of the line as (1.5,0.35). Name the line y = 0.35. Now press Create

Now, the new surface will appear in the list of surfaces. We want to plot the pressure coefficient across the wedge and the new line we created in order to determine the shock angle. In the list of surfaces, select wedge, symmetry, and y = 0.35. Press Plot.
