February 18, 2020, 03:46	Y+. How low can one go?	#1
Aveek Pal New Member Aveek Pal Join Date: Feb 2020 Posts: 10 Rep Power: 6	I have done a simulation over a NACA 0012 finite wing. The first layer height near the wall region taken by me is too low. The Y+ numbers achieved in my simulation has a lower limit of 0.04. I have used SA, k-w SST and transition SST turbulence models. Does anyone have any idea how this will affect the simulation? Is too low Y+ a thing? How does it affect the simulation other than the extra number of elements? Светлана likes this.
