Pressure-Outlet boundary condition for species
 
Dear colleagues,

Does somebody aware if it is correct to put species mass fraction equal 1 at the outlet-pressure BC while two species in the flow are presented? E.g. I have two inlets, one pure air and the second one of pure helium. Then how could I manage the BC at outlet for the species fractions? Is it wrong to put air species=const=1?

Thanks in advance.
