Hello my name is Mael and i need to use flow simulation for a Highschool project which contributes to my degree. So I have a problem with Flow simulation, Indeed, I created a fan and I would like to simulate the flow of the Air coming through the fan. Now, whenever I increase the speed of the rotating region, the flow of the Air doesn't change at all. That doesn't seem correct to me, If someone could help me please. Thank you for your answer, have a nice day.
