Dear Foamers,

I'd like to integrate my drag calculation along an axis (in this case the x-axis) in order to plot it over the length of my object. The drag (pressure drag) is calculated in the following way:

The calculator just computes Normals_X*p.

Now instead of integrating over the entire surface at once, I'd like to progress the integration in x-direction while storing all the intermediate values. These could then be plotted to obtain results similar to the ones I found in literature:

Your help is appreciated, thanks!
