defining mixture & defining mass fractions + AMG SOlver
Hello to all of you!
I am here to make a mixture of AIr + Licl solution + H20 vapor. These are 3 components & I want to add mass fraction in the boundary condition. In the screenshot, You can see its giving only two components H20 & licl but not giving Air.
What I am thinking , its gives only 2 components in this section & 3rd one (Air) is not showing. By default, Fluent will take the mass fraction of Air = 1- (MassFraction Licl+ Mass fraction H20). is it like this? Please clarify it.
Secondly, I have two ducts (I want to define Air + H20 in one duct while in the second duct Licl +H20. In this regard, I can define only one mixture. I am confuse how I can give two different mixtures? What I am thinking that I have to select all components (Air +Licl sol. +H20) in the mixture & then defining mass fraction, I have to kept Licl zero in one duct & air zero in the other duct. Is the right way to define it? Need suggestions.
Last but not the least, I am getting an error AMG Solver in the x momentum & AMG solver divergence in species-o. after interpreting the UDF , on running the simulations. One more thing I am here to add, model is working (simulations ) without UDF.
