Sorry I don't have more time to make helpful suggestions, but
Dear all,
I am afraid that boundary conditions imposed with the penalty
method are confusing NewtonSolver for a nonlinear system of PDE's I'm
working with (I have already checked the jacobians with
verify_analitic_jacobians...). Thus, I would like to rule out the
penalty method as culprit
Roy,
as always.
thank you very much!

Examples 13 and 18, the boundary_id() functionality. You can set ids
manually (and they'll be preserved on refined child sides), let

Hi,
Are there any examples that show how to apply different boundary
conditions to different parts of the domain?
I want part of the domain to have Neuman boundary conditions and
another part to have robin/Cauchy boundary conditions.
Is there a mechanism to distinguish that some faces of the fin

Hi:
I'm trying to implement Dirichlet boundary conditions in a 1D
problem using DiffSystem. There isn't really an example to cover this,
so I just want to verify what I came up with makes sense, where two
variables "B" and "lB" should be zero at the domain boundaries x=0,1
(note, using num
