Re: [deal.II] L2-norm gets decreased to certain value, but stays above threshold

I’m a bit confused by what you are asking. The entries in the residual vector corresponding to constrained dofs will converge to a non-zero number. Those corresponding to unconstrained dofs should converge to zero. As is stated in step-15 … we have to set to zero the elements of the residual ve

Compared to the target value? Depending on the values between ~1e-6 and 2e-3, but it can be larger, too. I will check the latter function and compare it to the current solution, but I thought by using ZeroFunction as boundary condition that then all boundary_dofs are set to zero. Am Donnerstag,

I assume so. My approach to ensure that is: I create a ConstraintMatrix called "Newton_constraints", initialize it as following: newton_constraints.clear(); newton_constraints.reinit(solution_relevant_partitioning); DoFTools::make_hanging_node_constraints(dof_handler, newton_constraints); VectorT

Yes, I forgot to clarify. I am calculating the l2-norm of the right hand side, i.e. which contains F(U) (when staying in the terminology of step-15). According to my knowledge that should go to zero, after that is the whole goal of the Newton iteration (if my understanding of the method is corr
