Hi. I have a L channel which has a 90 degree edge. I got an average of small y+, except at the sharp edge. I am thinking of keeping the same value for distance of first cell from wall, and use smaller value at the region of sharp edge. Can anyone advice me on how to do that? I am using polyhedral mesh with prism layer. Thank you in advance.

You can use a volumetric control to refine the mesh locally, and set its preferences to control the mesh refinement for the different meshing models. See the doc: Meshing > Region-Based Meshing > Volumetric Controls

Thanks for your advise. I got it!
