How I could to plot?
force drag vs lenght (model)
I need to know the behaviour the force drag along the lenght of my model.
I found the drag but it was global, with this expression force_z()@body.
I'm sorry my english is bad
I need your help, please help me

You are probably looking for the pressure coefficient. This is routinely drawn for air foil simulations, such as http://www.mh-aerotools.de/airfoils/...tributions.htm
Note that there is also a contribution from viscous wall shear. This is usually small in airfoil simulations as they run at high Reynolds number.
So a combination of pressure and wall shear will determine the force acting on the body. These parameters can be plotted against distance.
