Mach number
 

Hey

Do anyone have an idea how to get the Mach number I did my fluid as an ideal gas and I would like to find the Mach number using star-CCM+ is there is a way?.

mach number becomes available as a system field function when you go to compressible flow with idea gas so not sure why you cant use this so try doing a user guide tutorial like the subsonic slow naca-type intake one
