Does ANSYS-Fluent solve the Fay and Riddell equations for calculating Stagnation Heat flux in Hypersonic flows over blunt bodies?

Are the equations of Fay and Riddell embedded in Fluent or do they have to be imported using a UDF?

In Fluent, For a density based solver for steady flow, Is it sensible to have an option for Courant number (CFL no.)?

As usually the trend is a Courant number (CFL no) can only be used for a Transient( Unsteady) flow condition. Thank you in Advance.
