[immortality]

the runs were performing for 2 days but eventually stoped with these errors.
I use constant thermophysical properties as the case of shock wave.what may be the cause?

[immortality]

does errors come from thermophyisical model?

[lfgmarc]

Hi, this error comes from the iterative method used to convert the energetic variable to Temperature (see OpenFOAM-1.6-ext/src/thermophysicalModels/specie/thermo/specieThermo/specieThermoI.H).


Try to use a small time step .
