Yes, I am sure, because my case study is a flat plate and I use hexahedral elements (structural mesh) and cells have the same wall distance. I enclosed two figures of the mesh

Yes, "wall_dist" is the adjcent cell to the wall in "m" and it is exported from Fluent. The OMG_vis formula is based on y+ not y and y+ is a nondimensional parameter. Moreover, Omega depents on wall...

Replies: 38 Near wall treatment in k-omega SST Views: 56,645 Posted By behest OMEGA on the wall surface in SST model Dear all, I am working with Fluent and I have simulated a flat plate and the mesh is enogh fine (Y+<=1). The turbulence model that I use is k-w SST and I uncheck Low-Reynolds-Number in the...
