maxm no. of newton's iterations reached & parametric solver

Question about newton's iterations:

I keep getting the following error

Failed to find a solution.
Maximum number of Newton iterations reached.
Returned solution has not converged.

I am unable to locate where the solver is pulling up these Newton's iterations from. Can someone please guide me where to find the number for Newton's iteration? Also, any insight about why I am getting this error will also be very helpful.

Question about parametric solver:
I am wondering if there are any tutorials/examples that show me how to use the parametric solver. I am trying to use it along with a stationary solver because I am having convergence issues but I am not sure how to use it. For my problem when I choose to use the default solver, I get the iterative solver. So I am a little confused about how the parametric solver works. Should I be using it along with the iterative solver?

Thanks for the help.
