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) |
