Hello Everyone!

 

I'm currently trying to generate an enclosure/domain for a low speed 3D wing. Based on my research, a "C" Domain or a Hemisphere domain are usually used for such analysis. However, im not entirely sure which one would give better results or what the difference between the two domains are. Also, what should the size of my domain be, both upstream and downstream? should it be 5 x chord upstream or 10 x or 20 x upstream?
