Hi Foamers,

i am simulating the turbulent flow on multi element airfoils "30P-30N" that have 22inch=0.5588 stowed chord using OpenFoam.
my question is about setting the parameters of forceCoeffs function in ControlDict.

1- i should write "stowed chord" for three of them as "lRef" or not? if no, what i should write for "lref" for each of them?

2- as we know, the slat and flap of tree element airfoil, has 30 degree deflection angle. now my Question is that, what should i write for "liftDir" and "dragDir" for each of them separately?

i put my forceCoeffs in attachment, please please help me.
thank you very much
