Thanks for the great feedback. I will proceed with the DUNE solvers and I
might compare to the Eigen solvers for a simple setup.
I also considered PETSc as I use TAO (part of PETSc) to carry out
optimization, though I

Like I said I am biased as a DUNE developer (parallel iterative
solvers). But if you do not want to use DUNE, then I would rather
recommend PETSc, Trilinos or you will find others that might be more
suitable from Jack Dongarra's list

These sound like just the solvers and preconditioners that I need. Does this
also mean that flow is able to run in parallel?
No, it is not. But a variant (flow_cp) is, however it is still in heavy
development and

Just for the record, I found out that Eigen features a number of iterative

Hi again
I want to solve the fully implicit residual equations using Newtons method
with an iterative method for solving the linear system. I am using the
AutoDiffBlock objects and thus the matrix and right-hand-side is in the V
and M formats, or Array and SparseMatrix in Eigen, respectively.
