Hi,
I am trying to perform the mesh partition using the mesh generated from
GMSH. The generated mesh is quite big with around 500K elements.
I am new to deal.ii. But I get the impression that the
parallel::distributed::Triangulation works only from the
quadrilateral/hexahedral meshes and
I get it now. Thanks for your rely.
Best,
Wayne

This question might be silly. Is laplcae operator a positive definite
system and easy to solve? Does it become ill-conditioned when
mesh size and mesh quality reduce?
"ill-conditioned" and "difficult to solve" are two different things. The
condition number of the discretized Laplace
Hello everyone!
This is deal.II newsletter #245.
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:
#14886: improve docu of VectorTools::interpolate_boundary_values()
We could use the one above as a starting point.
I would argue that conda+python+jupyter is by far the most common
combination for those doing applied research and is getting installed in
many computer classes here in Europe.

Hello,
I‘m kind of lost in the nature of laplace operator.
Poisson equations are easy to solve numerically, and it has
type weak form.
However, in step-22
