Especially with BCs and domains' conditions and settings. Because the results seem not real to me. I don't know how to verify them at all.

I can't estimate is the whole workflow is correct. I mean, am I on the right way. For example, I have Outlet BC = 'Static pressure=0'. But I'm not sure that this will be correct for that kind of analysis . So I need someone to tell me that I'm right in this or visa versa - to tell me that correct BC is 'Constant speed' or some like that. The most important for me is the question of force. Will it be correct to estimate the Lift as stated (intArea(Force X)@bladearea) ? that the crucial point. And how to calculate efficiency coefficient of the blade?
