Hello!

I am analyzing a non-premixed combustion model (Adiabatic-Equilibrium). However, when solution converge and I get area-weighted average molar fraction, I tie up all products and it is not equal to 1. In fact, it keeps decreasing with O2 fraction in my oxidant. For example fr 40% O2, the total mole fraction is 98.8%. It equals to one when I use 21% O2.

Anyone may know what can be the problem?

Thanks.
