the unburnt gas temperature exceed Farve averaged temperature
 

Hi all
I use ECFM-3Z spark-ignition model to simulate the combustion process of a PFI high compression ratio miller cycle engine.
but sometimes these warnings worry me so much.
--------------------------------------------------------------------
There are 3019 cells the unburnt gas temperature exceed Farve averaged temperature.
*** Warning 104: Unburnt gas temperature 3.941E+02 K
exceeds Farve averaged temperature 3.941E+02 at cell
423596. Corrective action taken.
---------------------------------------------------------------------

Can any one here tell me how to solve this problem?
thanks in advance!
