Yplus values for walls in CFX4.4 -- CFD Online Discussion Forums

Forrest Guest Posts: n/a	Hello, How to work out the Yplus values for wall boundary conditions? For example, a structured mesh from CFX4.4, I know the first cell height of the mesh but not sure how to estimate Yplus values. What are the general criteria for the Yplus values using the wall function when two equations turbulence models applied (say k-epsilon model)? Thank you for your help. Regards Forrest
