Replies: 114 y+ and u+ values with low-Re RANS turbulence models: utility + testcase Views: 58,812 Posted By ArathoN yplus and ystar have different relations so they... yplus and ystar have different relations so they will obviously give different values. They have a comparable results only in the log layer because the assumption to define ystar depends on the log...
