When using multiphase flow mixture model and component transport model in fluent, why can't I determine the volume fraction of each phase in the multiphase flow inlet when I set the boundary condition of mass flow inlet? In a multiphase flow, the first phase is liquid water and the second phase is wet air, which consists of two components, air and water vapor. I want to set the inlet to be all second phase, i.e., the volume fraction of the second phase is 1, but I can't set the multiphase flow inlet.
