Hallo,
i want to calc the forcecoeffs with the "libforces.so" Library. I also got it to work but now i have a problem how the coefficients are defiened? i know the definition: c_d = (2 * F_d)/(rho*U²*Aref) In aeronautics the Aref is the area of the Wing from above ( projected area), and in automobile problems Aref is the projected area from the front. And for want do i need a lref? greetings, draufunddran |
