Multiphase Compressible Turbulence Model

Hi I'am trying to simulate compressible cavitating flow, there are various papers I have read stating you need to have the beta and beta* coefficients as variables of the mach number. Now I have tried using CEL functions to do this but get an error saying that the coeffs must be calculated to a constant value (and thus cannot vary). Is there any way to get around this?
Thank you for your time.

Variable constants is not implemented in CFX so it cannot do it.
But there is always a way. Have a look in the VARIABLES file, I think it is in the /etc/ directory. Find the beta and beta* variables and remove the bit forcing them to be constant values. There is a chance this will allow it, but be aware the limitation was put in there for good reason so there is a high probability this will not work.
