High drag coefficient Cd values

I've run my simulations and I want to extract the Cd values for my cylinder.
1) I added the following function block in my controlDict (same template which I found online). Quote:
3) I took the average of all the values and I am getting Cd values in the range of 16-20. May I know what is wrong? Or that shouldn't be the way I should be doing. Are there parameters I should change in the forceCoeffs block that are specific to the case that I am running? HELP! |
