Reply To: Doubt About Y Plus Value for Simulations

[Rob]

And to repost for the umpteenth time.... 

You're using CFD to answer a question. So, simulation is used to find temperature, pressure, bendiness, electrickery charge etc on a device. Does not quite meeting the y+ requirements offset against slight variations in geometry (omitted gaps or features), approximations in material properties and boundary conditions (do some reading on what the heat transfer coefficient really is) etc? Do those errors/omissions alter the end result sufficiently that you can't use it?
