Species transport does combustion without patching?
 

Hey there.
I am doing a combustion simulation, i am using propane air mixture for fuel.
I used 3 inlet there which were inlet fuel, inlet air and inlet vent.
But when i did the simulation the temperature increased but the co2 and h20 didnt occured and also i was not patching high temperature in any zone but the combustion still occured?

Is that case happened in species transport using eddy-dissipation model?
I need some help here.
Thanks.
