Hi Adriano,
Thanks for reporting this. The fix for this got put into the "primary"
PETSc classes, but not this one (again, this isn't exercised very much).
I'll put in a fix.
(As an aside: Hopefully in the next few days, I'll have an interface to
this in GRINS so we can exercise this in some test

Dear Roy,
I discovered that the example 1 of FEMSystem (NS equation) uses
NewtonSolver, that is, _diff_solver in libMesh::TimeSolver points to
NewtonSolver. Where should I change the code to use PetscDiffSolver? Is
there an example where I can take a look?
Thank you.
Best,
Adriano.

Thank you Roy for the explanations.
Best,
Adriano.

Thank you John for you reply and for the issue.

Nonlinear step: |du|/|u| = 0.99946, |du| = 194.712
That's only printed for intermediate nonlinear steps, IIRC. In later
time steps the problem is linear enough to converge in one
quasi-New

Dear developers,
I am trying to understand the FEMSystem framework, and the first thing I
did was to run the example 1, but the output I'm obtaining from the default
run (using make and run.sh) is completely different from the one in
http://libmesh.github.io/examples/fem_system_ex1.html
