We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

I agree that Y+ is high, however, it should still show a trend of a transonic spike in drag due to wave drag which again isn't the case. Intutition tells me Y+ would have a larger affect on viscous drag right? Running an invisid solution shows a similar trend of low pressure drag. And so far I have only compared drag coefficient.  I'll double check dimensional drag.  I also tried a Sears-Haack body with an analytical solution and the numbers don't align there either.  Regarding the help tab it looks like the site it takes me to is under maintainance for a few moew days.  Is that example a transonic example? Do you have a separte link to try?
