Error: divergence detected in AMG solver
 
I am entirely new to 'Fluent' so I'm not fully equipped with techniques to fix this problem. The screen keeps saying:

"Error: divergence detected in AMG solver: temperature"

I have increased the limits to the following: min pressure = 1000Pa min temperature = 298K

And I have set the Gauge pressure = 101325Pa

I am working with a compressible fluid.

Any solutions please???

Try solving the thermal equation under different relaxation factor. Set it to 0.8. If the problem still exists dicrease it at 0.5 and so on.
