No I'm sorry they're not. The reason BCs/projection/periodic BCs wasn't
immediately trivial is, mathematically, we can only enforce continuity of
the tangential components of the solution and IIRC the was a pain to do
consistently between 2D and 3D (at least enough that it wasn't something I
could
Hello Paul,
One more question, please. Are periodic boundary conditions supported
for Nedelec?
Michael.

Hello Michael,
If you want to estimate the error incurred due to
the use of the penalty method in a specific functional (say Q(u)), you
can do so by computing epsilon*Q( du/depsilon ). Here 1/epsilon is the
penalty we are setting. The function du/depsilon is the the derivative

No, thank Paul; reading further down the code it appears that I'm
wrong, and Paul *did* add some kind of vector-valued variable field
support to the Dirichlet code.
vector_fe_ex2/laplace_system.C seems to be our only example of it's
Thank you Vikram,
I'm solving the electromagnetic wave equation using Newmark system.
What are forward_sensitivity_derivatives that you are talking about?
Michael.

If you are worried about accuracy issues due to the use of penalties,
then there are ways of quantifying these pretty well using
forward_sensitivity_derivatives, when taken with respect the penalty.
Thanks.

Thank you,
the penalty method is what I'm currently doing.
Michael.

I don't believe so - the former predate the latter and at quick glance
the code seems hardcoded to expect scalar variable fields.
You might be stuck using a penalty met
Hello,
is it possible to apply dirichlet boundary conditions for Nedelec elements?
Thank you,
