Greetings Sir,

I've some more inquires regarding the rotation axis.
Based on my reading, Fluent is using right handed coordinate system , so the rotation will be counter clockwise on specified rotation axis.
Thus, based on this, I set my coordinate system to be (0,0,1) with 3008 RPM, as my blade should have normal rotation (counter-clockwise when viewed from the front).
I did my analysis, and by observing the streamline animation (on CFD-post), it shows that it rotates clockwise.
Then I did another testing, with (0,0,-1), with RPM 3008, the results of streamline animation shows its counter-clockwise.

Which is actually correct? The result is much different when its clockwise.

Kindly please advice. Thank you in advance.
