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:? Image: https://imgur.com/9FFcSLV |

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: https://www.pointwise.com/yplus/ Hope that helps. |
