I have a fully converged CFD simulation in Fluent. The total mass imbalance does not match with what i calculate on my own using surface integrals?

My combustion simulation is fully converged. The mass imbalance that Fluent calculates is 3×10^-9. However, if i calculate the mass imbalance from the average surface integrals, as...

Solution is converged for my cold flow analysis (methane-air) on Fluent, but the results look nonphysical ?

I'm simulating a cold flow analysis (methane-air) on fluent, using species transport model. The model has around 5 millions meshes with tetrahedrons and swept bodies. I use "realizable k-epsilon"...
