Grad and lift coefficient
 
Does anybody knows what these coefficients (Cl and Cd) represent, and particularly if these coefficients are scaled by the surface or not?

Re: Grad and lift coefficient
 
The definition of cd and cl are consistent with those in the interature. They are normalized by 0.5*rho*U**2*S (rho, U, S are density, reference velocity magnitude, and reference area all of which are defined in the "Report/Reference values" GUI panel.
