Hi there,

Could any one give a hand? I have no idea what is happening with the solver or the model. I am trying to model a laminar flow without any other physics. The default plots during solving progress are as attached. They are abnormal right? The model doesn't converge with 500 iterations, and I guess even if I increase the iteration number, the model will still diverge.
And could you please help me analyse the convergence plots? Just give me some basic ideas 'cause I am green hand yet. Based on your kind advice, I will adapt my model which has no complex physics but complex geometry. Thanks a lot.

Regards,
Ce
