Hello Foamers

I am trying to simulate a flow around a half-cylinder.In order to evaluate my result and i need calculate some coefficients non-dimensional numbers , like Nussel-number and the drag coefficient:

For the calculation of the drag coefficient of the geometry i should use this Formula :


with




I am using ParaView and Ensight as a Post-Processing Tool.

Can anybody explain to me, how and where should implement this Formula, in order to calculate the drag coefficient for every time step ?

Thx for the support

PS: I am using OpenFOAM 2.2.0
