Hi I am using Kepsilon Model Enhanced Wall function (the range of values for wall y+ should be between 30 to 300 )

The details of my Boundary condition

Pressure Inlet -4 bar
Pressure Outlet - 1 bar

3 BAR Pressure gradient in fluid domain

Attached is wall y+ value contour

Facet minimum at wall is 0.6
Facet max is 255
Area weighted average 20.85


As I understand minimum value should be 30 in my case it is 0.6(facet minimum) should I consider facet minimum or area weighted avg 20 to be less than 30 ?

Do I also need to enter something in supersonic inlet /initial gauge pressure for higher pressures say 10 bar so do i always just enter total gauge pressures
