      This is layer compression due to proximity. nPlease change gap factor in inflation controls. Please change it to 0.25 and check. nPlease see help manual for more details about these commands. nRegards,nKeyurnGuidelines for Posting on Ansys Learning ForumnHow to access ANSYS help linksnn

      They're all best depending on what you need. I tend to prefer smooth transition as the jump in cell size is lowest, but I don't deal with high speed flow so am less worried about first cell height. I also regularly run with 2-3 layers of inflation, or none at all as the high aspect ratio cell isn't suitably for my application. The meshing rules are really guidelines and there's a lot more to it than y+ and cell skew. n
