@Retsam one more thing I would like to ask was that the CFD analysis which you did for my project was based on a wind angle of attack of 180 degrees right ? I would also like to ask that if I wish to change my angle of attack , how would I be able to incorporate that effect in my CFD analysis ? I mean if I wish to perform analysis on a wind angle of attack of 45 degrees , 60 degrees, 75 degrees and so on and then compare the results. So is this possible?
