I'm doing a methane combustion calculation using Eddy Dissipation and I would like to know which variable I should choose if I want to display the flames by creating isosurfaces of 5 different colours from red to white in post. It doesn't have to be precise but "an artist expression" is good enough. I have tried with temperature but it does not look correct. What about conversion rate or similar? Anyone have an idea?

Do not know if I remind correctly, however as far as I remember there was something like ReactionName.Reaction Rate, wherein ReactionName should be something like Methane.... If remind I that correctly you find it in the large variable list only.

"Methane Air Mixture.Methane Oxygen WD1.Molar Reaction Rate" [mol / (m^3 s)] Thanks
