Hello,

can someone explain me the output from the newton iteration??

I want to solve a nonlinear problem and use

```
solve(F == 0, m, bc)
yh, ph = m.split()
```

And I have the following output. Can someone explain to me what this means?

No Jacobian form specified for nonlinear variational problem.

Differentiating residual form F to obtain Jacobian J = F’.

Solving nonlinear variational problem.

Newton iteration 0: r (abs) = 8.011e+01 (tol = 1.000e-10) r (rel) = 1.000e+00 (tol = 1.000e-09)

Newton iteration 1: r (abs) = 3.742e-01 (tol = 1.000e-10) r (rel) = 4.671e-03 (tol = 1.000e-09)

Newton iteration 2: r (abs) = 1.308e-03 (tol = 1.000e-10) r (rel) = 1.633e-05 (tol = 1.000e-09)

Newton iteration 3: r (abs) = 3.430e-08 (tol = 1.000e-10) r (rel) = 4.282e-10 (tol = 1.000e-09)

Newton solver finished in 3 iterations and 3 linear solver iterations.

Can i get the solutions output at each step?

And how is the start value chosen?

Thanks

Noya
