Ups, I've already answered to the first question.

Ok, I'm trying with NonlinearImplicitSystem in the first place.
I have a couple of questions...
Is it possible to compute and get the L2 norm of the increment as in example
13, it's a good indication of how the residual is decreasing and it's
cheaper to compute compared to the residual norm?
Would
Thanks for the suggestions, I'm going to try both the possibilities.

Hi all,
I'm solving the incompressible NS equations with a fully implicit dg code
and I would like
to know if there is an easy way to solve for the increment instead of the
solution itself.
Sometimes with non-linear fluxes building the residual on the rhs is easier
than summing
it to the product J*
