Hello dear foamers,

I esstimated first grid point thickness to be yplus~5.
I checked the actual yplus for the simulation and its ~0.5.

Is it acceptable? I mean the esstimated and actual is one magnitude of order in difference..

Thamk in advance,
Alex.

Can you give details about how did you estimate yplus, I mean which formula did you use?


Regards
Atul
