Hello,nInstead of attaching your images as a PDF attachment, please inset them directly to your post. Ansys employees are not able to download attachments on the forum.nRegarding your question - nAre you running a transient model? And this is an MRF simulation? nHow many time-steps have you simulated? Has your simulation reached a point where you will start seeing an appreciable drag value? How many flow-passes through the computational domain would air make during the time you just simulated? And do your results make sense.nDid you use the correct rotational velocity? By default, the units are rad/s.nKarthikn
