forceCoeffs function in control dict & multi element airfoils
 
hi dear foamers'

i am working on multi element airfoils and i use OpenFOAM for it's analyzing.
my Question is that, for setting the "lRef" and "ARef" in functions of forceCoeffs for obtaining the "cd" and "cl" on the slat and main and flap separately, what should i use?
the stowed chord of my airfoil (30P-30N) is 22 inch, i should this length for each 3 element?

please help me, your answer may help me a lot:)
Thank you very much.
