iftDir and dragDir in controlDict for three element airfoils
 
3 Attachment(s)
Hi Dear Foamers,
when we have three element airfoil. e.g the main element has 0 degree angle and the flap(another element of three element airfoil) has 30 degree angle.
what should we write for liftDir and dragDir in controlDict according to their angles?
