Hi I was reading in ANSYS help documentations that K-Omega is insensitive to Y+ calculations but that makes me ask how do you assess whether the near wall mesh is refined enough ? Is Y+ or Y* between 2 and 4.5 acceptable? Knowing that the viscous layer is between 0 to 5. Another ...
first of all - no, the y+ value for kOmega SST does not have to be around 1 or smaller. I'll try to give you a short explanation of my personal research about this particular topic. When standard kEpsilon model is used, the y+ must be greater than y+=30, which actually means t...

For turbulence modelling I use the kOmegaSST model. My mesh is a very fine one with about 30 boundary layers around my geometry(except the walls of the wind tunnel). As I said, laminar simulations work fine and Cdrag fits with my reference value. For k I use the followi...
I'm trying to use the LES turbulence model "kOmegaSSTSAS". I noticed some differences between the implemented version and the reference**. The main difference is the SAS source term in the omega equation: in the reference there is a (L/Lvk2)^2 (squared) instead of a simple L/Lvk2 ...
