Hi all,

I simulated flow over an aerofoil to get the forces and moment using Spalart-Allmaras turbulence model. The grid was done so as to achieve the y-plus values less than 1.0.

At zero degree I was able to keep the y plus less than 1.0 over the complete aerofoil but not the trailing edge-The aerofoil has a blunt trailing edge.

At 10 degree y-plus values at the leading edge were about 3.0 and were also larger than 1.0 at the trailing edge.

Since it is "good practice" to keep the number less than 1.0, I need to know how significant is the issue of not achieving this at the leading and the trailing edges.

Any help is greatly appreciated.
