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.

Hello,

Which turbulence model did you use? What are the controls (URFs) you set? Reduce the URFs and once stable residuals reached, turn them to default. Use FMG initialization. Also for higher order terms of discretization, please use High Order Term Relaxation (HOTR) for stable residuals. Use Psuedo time step.
