Hi, can someone help me about using the forces and forceCoeffs functions to calculate the lift and drag force coefficients for a simple 2d incompressible aerodynamic case? In particular, i'd like to know the meaning of the following parameters:

pitchAxis (0 0 0);
magUInf 289.16;
lRef 1;
Aref 1;

Thank you in advance
