I checked the 'remove invalid cells' dialogue and no cells were flagged for removal based on the default criteria. Assuming a minimum cell quality of 1E-8 is sufficient, there are no bad quality...

Pressure and Temperature out of Range

I have a simulation that was working before, but I refined the mesh to try and improve simulation accuracy. Now when I run, after only 4 iterations, I get the error:

Temperature corrections...
