Question

Our team has a bunch of planes that we ran through EFD but we need to know what exactly to put in for the various CFDs (Whats Alpha and My) We know what Fx and Fz are (Force of X and Force of Z) but whats My? If its torque around the Y-axis I don't understand why since it would essentially be lift.

    Ok so I found out what was what (kinda) but how do you change the reference point for the torque around the Y axis? I am assuming that the analysis program is just examining it around the origin (the last 2 CFD inputs are 0 0). Is that a correct assumption? or should we be manually setting the measurement to the center of mass?

    If you are summing moments about the origin, then use Ref_x=0 and Ref_z=0 in your rwdc Analysis program on the CFD card.
