hello all,
i am new on OF1.5,i want to simulate the naca 0012 wing , i have found experimental results in internet http://www.cyberiad.net/foildata.htm , also i found the parameter of the model, the chord length is 15.24cm, span length 0.91m . i have set my controlDict with forces and forceCoeffs. but i get wrong results , i dont know why ,could anyone help me check my functions _??
functions
(
forces
{
type forces;

// Where to load it from (if not already in solver)
functionObjectLibs ("libforces.so");

patches ( wall );
rhoInf 1.0;
CofR (0 0 0);

}

forceCoeffs
{
type forceCoeffs;

// Where to load it from (if not already in solver)
functionObjectLibs ("libforces.so");

patches ( wall );
rhoInf 1.0;
CofR (0 0 0);
liftDir (0 1 0);
dragDir (1 0 0);
pitchAxis (0 0 0);
magUInf 10;
lRef 0.1524;
Aref 0.1387;

}

are my lRef and Aref wrong? or any ideas?
