Hi

I 'm modelling a reactor in Fluent, the reactor consists of two channels in one channel a hot gas flows which provides the heat to the other side there is no reaction in there, I just put CO2 and nitrogen as the inert speices , but I have Speices mass imbalance between inlet and outlet? fro example some species that have zero mass fraction at inlet have some mass at the outlet !any suggestion?

Thanks
