Hello,
at the moment I am simulating our fsae car to look which setup whould be the best for us. I am looking at the range of the y+ value and the simulating time to get a realistic lift and drag value.
In every simulation I am doing the rear tire has a high y+ value in contrast to the rest of the car.. Why? And how can i remove this


Thank you

Thank you
You can refine the near wall mesh of the wall to reduce the high y+ value using the meshing features outlined in the Star manuals.

Please keep in mind, depending on what near wall treatment you are using you may have to keep the y+ value within a specific region to be valid.

I would recommend 30<=y+<=80
