I’m doing a CFD simulation to see the flow around a full sized scale model of a person and bike. No matter how much I refine the surface of my mesh, I continue to get y+ values near 800, and i need to get it down to between 30-100 as I’m using no-slip wall functions. Can someone inform me on what I may be doing wrong?
current set up:
Bounding box resolution: (20, 5, 10)
Surface Refinement: min, max (10, 10)
Feature Refinement: level 9, distance 0.005m, include angle 100deg
inflate boundary layer: layers 1, expansion ratio 1.2, min 1e-7, final layer 1e-4
the region refinement is split into three, with the other being level 0, then level 2, then closest to the bike level 3
Thank you very much
