How are you all ?

I have simulation, buts the problem is: it does not converge !!!!

so, where is the problem exactly ????

It's :

• Mesh,
• Under relaxation factor,
• or my physics characteristics in my simulation;

Please, I need your help

Usually it is either
1) Bad Mesh
2) Wrong boundary conditions being specified
3) Bad initial guess
there is also
4) You use completely the wrong models that are inconsistent, but this is rare because you often can still get a nice result even when you use the wrong models
