Dear all,
In my code I need to reconstruct the number of cells sharing an edge.
Is there a way to reconstruct this number locally? In principle I would
need something like to cell->line(1)->n_sharing_cells()?
Bests,
Nicola

Hello -
I noticed that the Trilinos ML preconditioner accessed through the
TrilinosWrappers benefits heavily from supplying the constant modes or the
null-space of the laplace operator. Using the extract_constant_modes
functionality I notice that this can take quite a bit of time for a vector
Oh! Sorry for bothered you, problem lies somewhere else - this topic can be

The program is suddenly terminated with exit value -1 so, I guess it is
segfault. It is very strange because the program works perfectly fine in
case 1), and after I swap coordinates between cell1 and cell2 (to get the
case 3) program just stop functioning.

Konrad,
What does it mean you cannot merge the cells? Do you get the wrong results?
Does the code segfault? Do you get an error message?
Best,

Hi all!
I've encountered a problem with very simple two-cells merging in 2D
(deal.ii v.9.0.0).
Lets say that I have two rectangular cells (for two different material) and
I want to merge it together and then refine those cells properly.
I don't have a problem with this when I want to merge
