      For two-phase calculations with mixture, ANSYS Fluent gives access to the acoustic & convective CFLs of the mixture. The sound speed of the mixture is based on the following formulation and the acoustic CFL of the mixture relies on a sound speed based on both phase properties. The acoustic CFL of each phase can be extracted using custom field functions (CFF). Such CFF can be used in all post-treatments, for example contours and reports. Please see attached document for further details.
