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; } |
