The purpose of the propeller, ideally is to suck air into it. So, basically I tried to do simulation only on the propeller, I used Frame Motion in setup. The flow direction is in ''result.png''. As you can see, the propeller keep blowing the air back into inlet as a reversed flow. However, when I put this propeller into solidworks flow simulation to have a test on its performance, it works completely fine and have a velocity outlet at around 30 m/s (swflowsim.png). So, I assume that it is not a problem associate with the propeller itself but it is about the setup in fluent. Can anyone help me please? I will reply really quick.

In cell zone condition, ''Inc'' is the cylinder of rotational region for the propeller and ''Outc'' is the control volume. Also, the velocity inlet is set as 1.8 m/s.
