CFD Online Discussion Forums - janafThermo Error on coalChemistryFoam

Dear Forum,

I'm testing the coalChemistryFoam-Solver on OpenFOAM-1.7. There i got a small case, i.e. a tube with only one Particle of coal, i want to track devolating and combusting. Therefore I'd like to simulate coldflow first. But everytime is start the calculation, i get this errormessage:

===============================

So I'm "out of range". My Temperature seems to be not within the borders of 0 -> 5000K. But my T-file is set-up with an internal field of 1300K and zeroGradient at walls/patches.

So where could be my error? Setting the calculation/fv-Schemes to Gauss linear uncorrected or limited doesn't seem to gain some success.

The code seems to read the "scalar T" (I guess from my T-file?) and compares with the borders - but where can be the fault?

With best regards,
