A comment from your post said:

The standalone AeroDyn driver input file can be set up to run multiple cases for different wind speeds (WndSpeed), rotor speeds (RotSpd), and pitch angles (Pitch) via the "Combined-Case Analysis" options. You can include the rotor aerodynamic torque in the AeroDyn output file by including "RtAeroMxh" in the output list (OutList) in the AeroDyn primary input file. Simply run multiple cases and take the time- (or, preferably, azimuth-) averaged torque to find the RtAeroMxh as a function of WndSpeed, RotSpd, and Pitch (or the like).

Enable me to know somes stuffs:

-If i can fixed RotSpd, Pitch and i varies the WndSpeed and then i calcultates the slop of the torque-wind speed, which is the coefficient where i searched. After i did the same for RotSpd and Pitch. My question is if this stuff is true in which values i fixed the variables (RotSpd,Pitch when we change WndSpeed;WndSpeed,Pitch when we change RotSpd;and WndSpeed, RotSpd when we change Pitch), if at the optimum values or at the initials conditions?

-Or i change arbitrary the triplet to form the 3D surface and then we conclude the slope according to each axis, if the case how many simulations can suffice to find the aerodynamic torque exerted on the Wind turbine

i would appreciate any suggestions from you
