It's really not *my* program any more -- more than 250 people have contributed
to it by now :-)

Hm, that's really quite unfortunate. It took me a couple minutes of looking
into the code, but I *think* what is happening is that the Arpack
Hello Vachan,
Sounds like you're implementing nodal DG, hence why you only need values
and gradients at the *quadrature* points from the neighbor. Something you
might want to consider rather than communicating them at solution points,
in case you ever decide to overintegrate.
You could still a
Dear Felix,
by any chance, did you take a look at step 10?
https://www.dealii.org/current/doxygen/deal.II/step_10.html
This step explains a little bit what to do when you want to solve on curved
domains with high order finite elements. In particular, you need to ensure that
the mapping you ar
Thanks for your answer !
I'm working in 2D on a disk !
This is my mesh on the 4 cycle of refinement (which I never use in practice
because it's not refined enough for what I want to do).
I don't think I have a mapping object...
What i do to initalize my system on phi is :
//On génère le dofhan
A quick question, since you are working on a sphere, are you specifying a
mapping of the same order as your phi?
