How to plot exactly Y+ number?

James Lewis

HI experts,

 

I do a CFD analysis and want to plot the Y+ number.

But there are many Y+ number ( the image below).

Anyone can please explain what is each Y+ number mean?

Many thanks!

Those first four quantities with YPlus in the name in the Plot tool come from the surface statistics output - Minimum, Maximum, Standard Deviation, Uniformity - on the surfaces selected.

The last item - Surface YPlus - is what you would typically want - this would give you the average YPlus on the selected surface.  Note that YPlus in AcuSolve is computed/reported at the first node off the wall, not at the center of the element.

If you want a contour of Surface YPlus, you would use the Post tool.
