Hello,

I attachment the results that i have in a process steady-state . With this results (unchecked residual checks) the residuals appear stable and the temperatures appear that it looks like they are going to continue like this. My doubt is:

With these results, can I consider that the model is correct?

Can I consider that the process has stabilized and is stationary?

I'm sorry, i think i attach as image.
The pictures were:
Thank you

You had attached the images, we're having problems loading stuff on this side. I think IT are messing with things they shouldn't....
The residuals aren't converged, but suggest the solution isn't changing much. However, as the monitors are still changing I wouldn't trust the results. Are you monitoring any other points, and velocity anywhere?

My system was a steel plate to which solar radiation is incident. I have also simulated the heat transfer which is the second variable I'm interested in after the plate temperature, and it seems that the heat transfer is stable, I introduce image:
Do you think my model would be correct?
Maybe the temperature should stabilize horizontally as it's steady state, but on the other hand FLUENT does not stop radiating 887 w/m2 , so it would be logical that the temperature continues to increase as in the first graph I think...
Could you help me please? to know if it's right.
Thank you very much for your help

I think it's still converging - the lines look flat as they're not changing much. Give it another few hundred iterations and review then.

In 1000 iterations, the form is the same, appears:
Can I consider that the process has stabilized? and, if it's true, as the temperature depends of the iterations, How many iterations i select?
Thank you very much

Until it stops changing. Have a look at the flow and temperature field to see what's going on.
