Okay in regards to your question, I had a look at other projects,
and as long as the point is in the right location your simulation should be fine. The MRF zone will use this at the center of rotation.
The Vector/rotating Axis itself will always stay at the global coordinate system. Please use the right-hand rule to define the positive rotation direction to determine if your object is spinning the right way around.
Thank you so much,
I did the same cnter of rotation for other simulation but the result is not right,
I was trying to use the AMI zone but the failure was their of every try.
Is there any a quick or even long course for how to be an expert on SIMCSALE
Are you sure that you have the right simulation geometry,
For me, the results seem quite possible for a flat blade. Usually, these blades are at an angle so that the air is getting “pushed” up or downwards. which you can also see in the figures of the reference.
