Reply To: k-w model and y+ value and EWF(Eulerian wall film) with DPM

Not a simple question, and something to ponder. 

If I set y+ = 1 how high is my first cell layer. How thick is the film? If the film is thicker than the cell (or thick relative to the cell height) is the thin film assumption correct? 

If I have a coarse near wall cell, how good is the particle trajectory calculation and/or velocity value taken by the film?
