I am facing some issues with viewing the mass fraction of Nox species in CFD - Post processing. The variable name isn't present in the drop down list of the species in the post processing interface.
The system is a partially premixed combustion of Hydrogen. Initially I used a cold flow (Species transport model to converge then selected the partially premixed model). When I selected the species transport model it displayed that all the pollutants will be set to 0 but I thought this will over written as the partially premixed model is selected.
Interestingly, I am able to see the contour of mass fraction of no2 in the Fluent interface of the post processing but the image quality is very bad.
Thanks in advance.

Did your run with Fluent? Are your there able to see the Nox fractions? I guess you are using the NOx pollutant models. I think you need to add the NOx related quantities for export to CFD-Post (under File Export ) and change the Data File Quantities in Fuent. The quality image might be related to your graphic card / old graphic driver or missing graphic card (check: https://www.ansys.com/-/media/ansys/corporate/files/pdf/solutions/it-professionals/platform-support/graphical-display-graphics-cards-tested-192.pdf?la=de-de)

Thanks a lot for the solution. It works like a charm. Yes, I did run with Fluent 18.2.
Thanks and kind regards,
