Thanks for chiming in, Phil. My goal was to validate the simulation against a problem with known result. Flow should hug the template until very late. (It must separate eventually which is probably why late tail chopping does little harm IMHO.)
I first ran a cylinder, hoping to see some regime change as a function of Re but no dice. That's when I switched to foils before giving up. (To its credit a pure white image produced a clean flow field.)
Unless parameters can be tuned by someone more talented than yours truly, I'm inclined agree with Chernyshenko that these (finite difference) simulations are a toy for art not a tool.
