Maximum number of iterations exceeded when calculating temperature from a thermodynamic potential

Error - Maximum number of iterations exceeded when calculating temperature from a thermodynamic potential. This may be caused by low-quality mesh producing unrealistic pressure in a few cells or inappropriate boundary conditions, fluid properties or time step. Inspect fields for large values in the last time step.

Hi,

This documentation page contains some lines of action to tackle this error:

I can see that you already tried a CHT v2 model, that is a good start.

Yes I have tried it but it’s taking more time than more. Is it normal or not?

The simulation is taking a long time to solve because you specified a total of 1000000 iterations for it (which is definitely way too much).

A good starting point for a simulation would be 1000 iterations only.

Cheers

Thank You @RicardoParis

Still I am having problem with the very first issue.
