Hi everybody,
Does deal.II provide a way to use Gauss-Lobatto-Chebychev quadratures when
using FE_DGQArbitraryNodes<2>?
Specifically, I want to integrate functions f(x) using Lagrange polynomials
on the GLC support points.
The quadrature there is usually defined with a weighting function, as \in
Hi,
I have started the implementation of such a class.
The only problem is that currently there seems to be no
parallel::distributed version of hp::DoFHandler.
Calculating smooth gradients over the whole domain with your method would
be way too costly, I guess.
So I am going to have to wait un
Dear developers,
can you already foresee when there will be a version of hp::DoFHandler that
works with parallel::distributed::Triangulation?
Best,
Andreas

Hi everybody,
I am currently implementing a semi-Lagrangian advection solver in deal.II.
Everything works fine in periodic domains, but now I want to define
boundary conditions that depend on the gradient of the solution at the
boundary.
When I use Lagrangian FE_Q elements, the gradients are di
Hi,
I have just encountered an issue with projecting points into a cell.
Say, I have a point x which is very close to a cell (e.g. distance =
10^-16) and I want this point to be inside the cell. My first attempt was
to map the point to the unit cell, round the coordinates to 0 or 1, and map
