Hello, I have compiled buoy
 

Hello,

I have compiled buoyantFoam solver after adding transport equation and included the hCombustionThermo class instead of basicThermo. The compilation has been successful. But for a simple 2D case with one specie the case gives the following error.

FOAM FATAL ERROR : attempt to use janafThermo<equationofstate> out of temperature range 200 -> 5000; T = -37.5747#0 Foam::error::printStack(Foam:http://www.cfd-online.com/OpenFOAM_D...part/proud.gifstream&) in "/home/caelinux/OpenFOAM/OpenFOAM-1.4.1/lib/linuxGccDPOpt/libOpenFOAM.so"

Actually, the error doesn't make sense to me as the temprature inside the while domain is atleast above 300K and it cannot go below 0 K.

There is some problem with the numerics which I am not able to find... I have seen people facing the same problem. I tried to increase the number of orthogonal correctors with no change in the results.

I just want to know as what is causing such problems?

The mesh is pretty generic... With hex cells.
