help me ????

thanks .... my dear friend , Who can solve my problem ?? Now . i have four species (include hydrogen ,oxygen,water vapor,nitrogen) in my model, Today , i simulate two mixtures to react in differen t channel respectively *****FOR EXAMPLE********************* **First mixtures** : include hydrogen ,water vapor **second mixtures**: include oxygen , water

vapor ,nitrogen How to define the order the react in "Define/ Materials/Mixture species"" in my way : i arrange the species of react [[hydrogen,oxygen , water vapor , nitrogen]] in the "Define/ Materials/Mixture species"" . i defined mass fraction of the first mixtures in the first channel ((hydrogen 0.72 , water vapor 0.28)) because i want to simulate two ideal gas (hydrogen , water vapor)flow into first channel in the ""Define/Boundary condition " , so mass fraction of oxygen is zero . no oxygen flow into this channel Reversely . i defined mass fraction of the second mixtures in the second channel ((oxygen 0.22 , water vapor 0.023 , nitrogen 0.757 )) because i want to simulate three ideal gas (oxygen , water vapor, nitrogen )flow into second channel in the ""Define/Boundary condition " , so mass fraction of hydrogen is zero . no hydrogen flow into this channel
