cross flow over a cylinder
 

Can anybody help me on this. I am trying to run a simulation of steady, laminar flow of air around a circular cylinder in cross flow placed in a duct. For this purpose I have created a 2 dimensional mesh in GAMBIT 2.2.30 and solved it in FLUENT 6.3.26. I have kept the density of air constant.When I plot the variation of pressure coefficient across the cylinder I get a value of around 1.4 at the stagnation point whereas the exact value is 1.
