Dear David,
The solution is indeed quite simple, You can make a loop in your python
script and limit the Newton algorithm to only one iteration each time
(and control that the convergence was achieved or not by the "converged"
flag returned by the solve function).
Best regards,
Yves

Dear getfem-users,
My issue is quite straightforward.
I am using Getfem to solve nonlinear problems and i would like to
retrieve the solution at each step of the Newton method, not only the
solution obtained at the convergence of the algorithm.
Is such a thing even possible using the python interface?
Another alternative would be to implement one's own newton solver in
python while relying on the model methods to extract the tangent
matrix/rhs.
Is it the correct approach or is there a better way to do it?
Kind regards,
David.
