Hello everyone

When running calculation about 25 iterations.
The console says:
Stabilizing temperature to enhance linear solver robustness.
Stabilizing temperature using GMRES to enhance linear solver robustness.

Divergence detected in AMG solver: temperature
Error at host: floating point exception


I have tried modify: 1.stabilization method 2.URF 3.initialization method

But there is not much change to the iteration.
(The attach pictures are my fluent setting, iteration and my mesh)
Could someone give me some advice?

Thanks
