Hello,

I am solving a model using SST turbulence and automatic wall treatment. I see that the maximum yplus must be less than 200 from the solver guide, but is there a minimum y+ value recommended for adequate near-wall modeling?

Thanks for your help.

hi,

You will run into problems with very small y+ as round-off starts causing problems. When this happens is problem dependent. Need to do a sensitivity analysis to establish if it is important.
