Hi everyone,

I am trying to simulate the non-premixed combustion of an industrial burner and I am having this message throughout the whole simulation. The number of cells affected vary from iteration to iteration but I can´t seem to get rid of it. After the simulation is "converged", there are around 30,000 cells affected out of 3M.

I´ve read through other threads with similar issues but in my case the simulation is converging to what appears to be a correct solution. The temperature contours look good but I am not completely confident due to these messages.

I have been monitoring the minimum temperature in the domain and it appears to be 2 K smaller than the temperatures I set at the air/fuel inlets (Tinlet = 291.15 K) while there is no heat taken from the domain. All boundary conditions are temperatures taken from a Berl combustor simulation. Can anyone help me with this?
