Default AUSM+ low Mach

Hello,

I have a question for the implementation of the AUSM+ scheme for low Mach numbers flows.

If we modify the speed of sound at the interface as suggested Liou, for which Mach numbers we must use the preconditionned matrix \Gamma ( for exemple the weiss smith matrix) ?

Does anyone has some remarks for the implementation of the AUSM+ scheme ??

Thank you
