You're right about the high aspect ratio cells. I was trying to obtain fine enough mesh near the airfoil and the ground, and the aspect ratio of the cells near the inlet reaches 1e6... But the red...

Abuout turbulent viscosity

Hi everyone:
I'm calculating a case with an airfoil flying in ground effect. The height, h/c, is 0.01, and Re is about 2e7. Everything looks alright, except that the turbulent viscosity is over the...
