Pressure Coefficient in CFD-Post
 

I am looking to setup Cp in CFD-Post and I am running into issues. These are my current steps:

I create a new expression called Cp1
(2 * (Pressure - 0 [pa])) / (1.225 [kg/m^3] * (45 [m/s]^2)

Then I created a User Defined variable called Cp using the expression Cp1.

I continue to get errors. Any help would be fantastic.

Thank you for the help fellows!

Figured it out. If anybody has the same issue, found the solution in the CFX manual.

(Pressure - Reference Pressure ) / (0.5 * areaAve(Density)@inlet * areaAve(Velocity)@inlet^2)
