How to improve locally the Y+ Value?

renee · September 30, 2013, 03:57

Hello everybody,

my current case shows a y+ range of 0.0003 to 4.86. Since the region of the high y+ value is very small, I would like to decrese just the y+ value in this region. If I would just decrease the percentage of base- prism layer thickness, the small y+ values would drop even more which I would like to avoid. Does someone know a good strategy how to handle this?

Thanks in advance

René

hi; it´s necessary to know the velocity in every part; so in every part will be a boundary layer first .
