Dear all,

I am using simpleFoam to solve a steady incompressible low speed flow. It is similar to cylinder flow. The air speed is about 27.5 m/s. However, the Cp I got at the stagnation point is slightly greater than 1 (between 1 and 1.08). We knew that Cp should be less than 1 for the incompressible flow. Does anyone know why this happened? What I did wrong? or I should not to worry about this. Thanks.

Quinn
