Lift and drag

Hi,

I have made a wing in caedium and I suceeded to plot the pressure coefficients over the wing.
Now i want to plot the amount of lift and drag and the lift and drag coefficients in a graph, to determine the performance of my model. How can i do this in caedium?
I studied on different tutorials and i think i have to create and add a new kind of result, but i dont have a clue of which scalars or vectors the new result must be composed from. Can someone help me with this?

Derived from force

Lift and drag coefficients are derived from Vector Variables->F (force) on the Results Tool Palette. For more details see the comment "Lift and Drag Coefficients."
