26.9 Yplus/Ystar Adaption

FLUENT provides three different options for near-wall modeling of turbulence, standard wall functions, nonequilibrium wall functions, and the enhanced wall treatment. As described in Section  12.11, there are certain mesh requirements for each of these near-wall modeling options.

It is often difficult to gauge the near-wall resolution requirements when creating the mesh. Hence, Yplus and Ystar adaption have been provided to appropriately refine or coarsen the mesh along the wall during the solution process.
