soheil_r7 New Member Soheil Join Date: Mar 2014 Location: Helsinki Posts: 21 Rep Power: 12	Hi. I'm trying to investigate flow around a delta wing in supersonic flow ( Mach Number = 1.4 ). the biggest problem i have is correct y+ value domain in Spalart-Allmaras turbulence model. I calculated Y+ Wall Distance using the CFD-Online tool. I attached a picture of my Y+ plot and y+ min and max values. Do I have to change my mesh for better y+ or this current one is good? According to the fluent help ( picture attached ), is there any specific y+ range for SA model? I really appreciate any help. yplus_minmax.jpg yplus_plot.jpg fluent_help.jpg
