February 8, 2022, 00:37	In Non-premixed model getting undefined species in different inlets	#1
johnleo New Member Pritam Dey Join Date: Apr 2020 Posts: 9 Rep Power: 6	Hello there! I am confused with the fact that in my fuel and air inlets there are a very small fraction of other species which I didn't define as my boundary condition. For example- If I set Methane in the fuel inlet (Mean mixture 1), after running the simulation there are small fractions of CO, H20, etc. I couldn't find the reason anywhere on the internet. Your help would be much appreciated. Thanks.
