Plot mole fraction of species in multiphase model

      Hi,


      I would like to visualize the mole fractions of the species in my multiphase model. I know how to plot the mole fractions within one phase. Now it would be extremely interesting for me to know the mole fraction of a species relative to the entire amount of moles across all phases. Is there a possibility to plot this in Fluent? Like a mixture mole fraction or a mixture composition?


      Thank you in advance!

      You'll need a custom field function for this, Fluent will only report on the phase and not at the mixture level.

      Thank you for your help! So just to make sure I understand this correctly, I can define a custom function that calculates the mole fraction at mixture level taking the mole fractions at phase level and e.g. the volume fraction of each phase?

      With custom functions you access the solver data so you can code up pretty much anything. In your case you want a function of the volume (or mass) fraction of the species and phase.
