Thanks Rob, what value of Y+ would be suitable for this transonic aerofoil simulation? I have been told a Y+ of less than 1 is good but I am getting between 5 and 10 usually. I can reduce this Y+ by increasing the mesh bias but then my orthogonal quality value reduces to below the desired level. 

Its difficult to balance these quality checks. 

Thanks for the time.
