Hi,

Can anyone please let me know if they have experienced extremely high turbulence dissipation rates close to walls?

When I try to turn on Enhanced Wall Treatmenr it diverges then crashes.

Thanks Phil

Hi

Check the y+ value near the wall. For Enhanced wall Treatment, the value should be around 5.

Regards
