Let's set the reference values necessary to calculate the pressure coefficient.
Report > Reference Values
Select farfield under Compute From.
The above reference values of density, velocity and pressure will be used to calculate the pressure coefficient from the pressure. Click OK.
Display > Contours...
Select Pressure... and Static Pressure from under Contours Of. Then select Pressure Coeffient.

The pressure coefficient after the shockwave is 0.293, very close to the theoretical value of 0.289. The pressure increases after the shockwave as we would expectEnclosed streamlines at the back of cylinder clearly shows the recirculation region.
