Hi folks
I am performing a transient study and after 3000 iterations it takes place a divergence of residuals and so my results...

Is is:
Density-based
Energy On
Laminar Flow
Courant Number 0.1 (which works perfect)
Implicit
Second Order

Transient condicionts:
Time Step Size = 0.1 seg
Number Steps = 5000
Max Iter/ Time Step = 50


Everything runs well and behaves as supposed but when it reaches 3000 iterations....diverges!

Any advice?? is there anything else I can do??
Any suggestion??

Thanks in advance

Regards
