UDF for species mass fraction in a nonpremixed combustion model
 

Hello,
I'm currently trying to simulate a combustion environment using the nonpremixed combustion model.
I imported the mechanism for reactions and thermodynamic properties of all species and the simulation succeeded with no problems.

My question is: is there a way to hook up the values of species molar/mass fraction using UDFs?? I want to calculate particle formation in the reactor using species molar fraction

Thanks in advance.
