Reply To: Example of flow analysis with a Mach number of 10 or more on a Fluent Pressure b

Hello,

I believe Mach number greater than 5 calls for a hypersonic flow, as air molecules will start to dissociate at such high speeds. You might want to use density-based solver instead of pressure-based. I would also recommend you to use two-temperature model with cfd_hsf license installed on your system.
