Non-Reacting Mixture in FLUENT
 
Hello,

I'm trying to model the flow of a transient, non-reacting binary liquid mixture in a closed chamber and I ran into a question. I've set the individual components and their properties and then I've set the mixture properties as weighted mixing laws using the individual component's properties.

My question is: where should I set the mass fractions of my mixture? I've tried setting them under "initial conditions" in the solution initialization panel but I don't think the residual is showing up correctly. I expect to have a continuity residual for the bulk species as well as one for the remaining species. The continuity residual shows up correctly but the residual for the other species stays relatively constant at around 1e-12.

Any thoughts?
