JanafThermo error
 

Hi, im using dieselFoam to inject gas , c12h26, at approximately 1000K.
When I change the internalTemperature to 850 K I get this error.

--> FOAM FATAL ERROR:
[12] attempt to use janafThermo<equationOfState> out of temperature range 200 -> 5000; T = 6787.83

FOAM parallel run aborting

I have tried to improve the mesh at the injection inlet without success,
Does anyone have any idea?
