Dear deal.ii users,
is there someone who implemented Nonhomogeneous Dirichlet Boundary
conditions using a Dirichlet lift?
Thanks a lot in advance,
Kind regards,
Giulia

Dear all,
I am using the ParameterHandler class to select multiple parameters and
lists, but I don't know if I could have something like the following.
What I'd like is to specify multiple parameters that, sort of nested, have
a string and an integer. As a concrete example, I want to specify st
Hello Giulia
The usual way of applying Dirichlet bc in deal.II essentially does a
lifting approach. If
u = g on boundary
then the lifting is
u_{g,h}(x) = sum_(i on boundary) g(x_i) \phi_i(x)
Did you want to use a different lifting ?
Best

Hi
In a similar case I have used this function

You can use this twice to get the result you want, combined with

Thanks, Praveen.
I could use those, and in my tests that I've done now they work great, but
this means I won't be able to detect errors automatically. This deal.II
feature is the best thing, dropping it would be not so cool.
If not possible, I will just do this by hand.
Thank you!

Yes, we will be creating a PR for that soon.

Hi all,
I was testing my code, with method of manufactured solution.
I have a source term, which is vector value, defined as ..

Thanks, I understand what you meant!!

Add up this.. can I ask your intuition for my another problem?
I am using deal-ii to analyze Non-newtonian fluids, which varies viscosity.
For example, my viscosity eta is function of (u) field. I am solving this
with iteration method.. (Picard
