HI THERE
is there any need to model the blade and the atmosphere together for analysing the act of TRANSMITTAL of material of atmosphere affected by the blade?!
if yes should i define a solid domain for the blade and a fluid for the atmosphere?
so how can i define the rotation of blade? i cant define rotation in solid domain?!!!

You actually only need the fluiddomain where the blade is cut off. So in the middle of the domain the shape of the blade is missing. then you put a boundary condition "wall" to that boundary. then you can set up the domain as a rotating domain. so you actually let rotate the domain instead of the blade..
