Hello! Everyone! I have a question in Fluent, as you can see the following figure, for the Pressure outlet, if we set the species mass fraction=0, it means that we set the mass fraction equal zero in the case of back flow, but if there is no backflow velocity, so the mass fraction is non-zero, and all the species will come from the interior and can pass through the outlet to the outside, am I right? Thank you!
The following link is my figure: https://previews.dropbox.com/p/thumb...ue&size_mode=5 |

That is correct. In cases, you don't have any backflow, you can set it any values.
