HI is someone familiar with non premixed models in Fluent? I'm using Pdf equilibrium and steady laminar flamelet models, but i'm not able to change the transport properties for the pdf-mixture, it only gives me the possibility to set it as a constant or as a polynomial, but i'd like to set it as mass weighted mixing law

Mass-weighted or volume-weighted mixing law implies properties being dependent on the species fractions. This is not permitted in the non-premixed model for transport properties.
