We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Hi,

High Y+ values can affect the accuracy of your simulations, especially in cases where you need to capture near-wall flow behavior. To reduce Y+ values to around 1, you should aim for a finer mesh near the wall. Instead of bias, try for manual meshing near the wall.
