Hi,

I have used Surface/Polyhedral/Prism Layer and the mesh is 8 M cells.
Prism Layers = 20
BL Thickness = 0.1 m
Growth Rate = 1.3
Prism Layer Stretching = 1.2


I want to know whether my Y+ value for the mesh is below 1. So, first I created a XY plot and chose Wall Y+ against the iteration it didn't work. Then, I used the Report>Expression and chose Wall Y+ from the scalars and created a monitor plot but it didn't work too. Could you please tell how to find the numerical values for Y+ with the help of a plot?

Secondly, I created a scalar scene for Wall Y+, which shows that Y+ is very high only near-tip of the blade as shown in the attachment, how to fix it. Any suggestions? I have also attached the pictures for blade mesh.



Thanks for your time.


P.S: I am using K-Omega SST.
