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 gave you the wrong answer on October 11th, and I sincerely apologize. What I'm actually curious about is not why a wall function doesn't agree with a flux definition on an inlet, but rather why the surface integral of the total surface heat flux and the total heat transfer rate in the flux report output different values at the inlet.

I am attaching a screenshot of the phenomenon. Please take it into consideration. Thank you
