Hello,
I would like to help me for this:
Specifying mass fraction of species in fluent

I have model with two inlets.. one from which air enters...
and the another one for CO2 (from nose of person)
For the air inlet no need specify mass fraction, is that true?
How to specify for the mass fraction for CO2 inlet? From;
Model- species Edit
Species transport (air-co mixture template) Air-carbon monoxide
(No reactions)......is that true?
But in boundary condition; what is the number should be opted in CO2 its 0.95 or what?
Thank you
