Hi,

Make sure that the boundary conditions for the species transport equation are correctly set. Check the injection boundary conditions, particularly at the submerged nozzle, and ensure that the mass fraction of CH4 is properly specified.

I suggest to use monitor to track the mass fractions of CH4 and N2 during the simulation. This can help you identify where the discrepancies are occurring and how they evolve over time.
