Mass fraction expression
 

Hi guys,

I am running into issues on getting an average mass fraction for a certain species at a boundary.

I get an invalid expression error. The expression typed in is:

Average(MassFraction(species="products"),["je-13-inlet"],Weight="Area")


the simulation is single-phase, but has species transport, with only 2 species: 'products' and 'air'.

Any ideas on what's wrong with the expression? I am using Fluent R19

Thank you in advance!
