Rule(s) of thumb:

1. Use expansion ratio 1.2 at max and for transition critical flows lower values to 1.15 or 1.1

2. For fully turbulent flows you can use the Y+ upto 10, in that case you will...

mostly we are interested in min angle (>18 deg) , minimum quality (shoud be > 0.3) and expansion ratio. Mostly these parameters are viewed from solver point of view.

There is very nice...
