Y-plus calculation?
2 Attachment(s)
Hello,
I am trying to calculate y plus for a drafttube as on picture. I understood that Y plus will be only calculate to the wall (boundary condition) of the domain. I calculated on post-CFD after I wrote the definition: ave(Yplus)@ Diffuser Default ''Diffusor Default'' it is the wall of the draft tube. Do you think that I am cacluated in the right way or? shall i write in this way: areaAve(Yplus)@ Diffuser Default Do you have any idea how to make a chart of Y-plus through all the drafttube? I make a counter and use counter to show y- plus through all the draft tube, I attached picture on it. I used ''K-epsilon models'' . It seems that Yplus is very low in the counter so I wonder if I am doing right? |
Why do you need to make an averaged value for Yplus?
what is it good for? As far as I know, A distribution (contour) of Yplus is needed to judge the quality of mesh near the solid walls. |

The average value of Yplus is not helpful at all!
As I see the attached contour, there are regions with the Yplus of more than 200. It means that you need to select lower thickness for wall-adjacent cells at these regions. |
