"The basic idea behind the scalable wall-function approach is to limit the y* value used in the logarithmic formulation by a lower value of 11.06 is the intersection between the logarithmic and the linear near wall profile"

These are the statements from help files of cfx.

The lower limit of y* is restricted to 11.06,does this mean that the linear near wall profile is neglected?

"Do not use Standard Wall Functions unless required for backwards compatibility."

These are the statements from help files of cfx.

what is backward compatibility?

I am trying to simulate a heat transfer problem, how does scalable wall function affect the results?
