Is there a code that solves for example du/dx + du/dy = 0 with a DG formulation?
Yes, this is the advection equation, and you can find a DG solver in step-12
if you set the vector beta=[1,1] there.
I was wondering if there is any interest in creating a Space-Time DG method
Hello everyone!
This is deal.II newsletter #214.
It automatically reports recently merged features and discussions about the
deal.II finite element library.
## Below you find a list of recently proposed or merged features:
#13884: Use map::find rather than insert to avoid creating temporary
Thanks for your suggestions, especially the different underlying concepts
for the serial and p::d::triangulation, which makes it hard to compare the
results 1:1; that clarified my doubts.
Best, Maurice

I was wondering if there is any interest in creating a Space-Time DG method
with deal.ii? The interesting aspects would be a larger temporal step and
the ability to use Cuboids, or prisms, with the

The third formula.

Hi everyone,
I think the following formula is wrong for the position of the first left
square bracket: \sum_{q}[\J^{-1}(\hat{x}_q) rather \J^{-1}[(\hat{x}_q)
Hi,
Yes, I have found that the code works with periodic boundaries if I don't
refine and it works if I use other boundary conditions with/without
refinement. I can try periodic boundaries and then refine every cell and
see what happens.
I understand it is almost impossible to find the problem
