I am making my 2D airfoil simulation using openfoam , and i ve calculated the Cm,Cd,Cl Coefficients But i still wanna know how Can i calculate the Cdp (Drag Due to pressure Distribution) in OpenFoam.
It's very simple. Instead of going for forceCoeffs, you can go for forces. Later, use the pressure and viscous components given in forces data file to manually calculate the drag or lift coefficients components.
