Now that the derived part has been created, you will set up a new plot of pressure coefficient against x coordinates of the new derived part.
In the bluntBody window, right-click on the Plots node and select New > XY Plot.
This creates a new empty plot node in the tree and displays it in the Graphics window.
To select the part on which to plot, open the Plots node and select the XY Plot 1 node.
In the Properties window, click on the right half of the Parts property. In the Select Objects dialog, make sure that the previously created plane section is in the Selected list. Click Close.
To set the variable to plot on the y-axis, open the XY Plot 1 and Y Types nodes, and select the Y Type 1 node.
In the Properties window, check that the Type property is set to Scalar. Then open the Y Type 1 node and select the Scalar node.
Set the Scalar property to Pressure Coefficient.
For the plot to be accurate, the reference density, reference pressure and reference velocity of the Pressure Coefficient field function should match those of the Force Coefficient 1 report. This can be achieved by copying and pasting these properties from the report to the field function.
Open the Tools and Field Functions nodes, and select the Pressure Coefficient node.
Copy and paste the values of Reference Density and Reference Velocity from the properties of the Force Coefficient 1 report to those of the Pressure Coefficient field function. (The Reference Pressure property should equal zero for both objects already.)
In order for these changes to be reflected in the plot, you must initialize the solution. To initialize, click on the 
(Initialize Solution) button in the toolbar or use the Solution > Initialize Solution menu item.
The plot will look like this. (If you resized the display the axes may look different from the ones in the illustration.)
Save the simulation.
