I am trying to do flow simulation for a shuttlecock that is spinning and flying at an angle to the flow field.
I have set the domain on cfx-pre as rotating. The shuttlecock is a non-slip wall as taught by the tutorial. I also set the shuttlecock as rotating under boundary. However, I don't understand how to set the others, like inlet, outlet and other sides of the box of air. 1. Do I set the inlet and outlet as rotating or stationary? 2. Since the outside wall is set as a free slip wall, it really does not matter if it rotates or stationary right? 3. Short of creating a geometry file for each angle of attack, can I just modify the inlet condition or? How should I go about testing different angle of attack? 4. If I change the flight angle through the way the shuttlecock is positioned in the box, then when I set the rotation of the wall, will it mean that my shuttlecock will now cocksrew instead of really spinning? |

I tried setting the inlet velocity as cart. and giving it velocity in 2 directions to simulate airflow with angle of attack. It seems that I am having issue with the flow not flowing out...causing error. How do I fix this?
