janafThermo Error (FEM / Genormte Berechnungen/OpenFOAM)

Hallo ans Forum,

ich arbeite mich gerade durch den coalChemistryFoam Solver und möchte zu anfangs nur einen simplen 'coldflow' simulieren. Also ohne Reaktion, nur ein inertes "Ash-Partikel", um die Partikeltracking-Eigenschaften zu begutachten.

Allerdings bekomme ich dauernd folgenden Fehler, wenn ich den Solver starte:

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

Ich bin also mit meiner Temperatur "out of range". Was ich mir aber lt. BC nicht vorstellen kann, da ich dort ein internalField von 1300K habe. Wenn ich in den 'coalCloud1Properties' rumspiele, und zum Beispiel die T0 verändere, komme ich oberhalb von 1365K auf Werte knapp über 500, darunter auf Werte von -1e6.

Wie berechnet das janafThermo(I) die Temperatur dort? Bzw. wo liegt mein Fehler?

MfG,
