Dose anyone know how can I set up the Prism Layer Mesher in trailing edge?I use Polyhedral Mesher,Prism Layer Mesher and Surface Remesher.

I have tried to set up Prism Layer Thickness,Prism Layer Stretching and Number of Prism Layers,I can get y+ < 1 in every where except trailing edge.
How can I fix it：困惑：?

Hello

Have you tried using the 'Wall Thickness' function instead? This allows you to define the height of the first cell at the wall. This value can be estimated for a corresponding value of y+. So if you calculate it for say a y+ of 0.1 or maybe even 0.5, then you are almost guaranteed to achieve an over all Wall y+ value below 1.

Here is a link for an online first cell height calculator:

Hope that helps.
