Hi, I know that this is a really common thread topic, but after looking at these threads and sites (among many others):

http://www.cfd-online.com/Forums/ope...lref-aref.html

http://www.sourceflux.de/blog/lamina...ound-cylinder/

I know that lref is the reference length and Aref is the reference area but I am so confused on how to set these correctly. I am getting non-convergent drag values on the order of 10^6 and I've been trying to understand where I'm going wrong!

Can someone please explain to me how to correctly set lref and Aref?? I've been reading so many different things I am thoroughly confused on how to set it for my case. My cylinder diameter is 6 m, the cylinder extends down 10 m below the surface and up 10 m above the surface. I am using waveFoam.

Please help!!
