Hi all, I model coal combustion problem and observe strange phenomena while solver is running. Some temperatures fall to absolute zero on certain iteration. And solver breaks down. Do you know what is the reason and who to avoid it?

Thermodynamic data would be my first suspect. Check heat capacities, latent heat etc.
