Hi!
I have a question: how did you estimate the reference area value for the drag/lift coefficients control?
When having a look at it, I’m getting a different value than yours:
I would also recommend adjusting the layer settings a little better. Currently we have y+ values which are too low:
Having such low y+ values in the region where the air separates will definitely cause issues. Basically the boundary layers need to be a little thicker (30< y+ < 300 if you’d like to use wall functions) or much finer (y+ < 1 if you want to use full resolution).
PS: a validation case on the Ahmed Body was released not very long ago.
Cheers
