I want to postporcess some data across an interface with feInterface.
I have a fully::distributed::triangulation.
I am doing is something that "roughly" looks like this:
template
void TSL_prllel::interface_gradients(Tensor<1, dim> &
interface_gradients)
{
interface_gradients = 0;

This works with a single MPI but not for more. Is it because the cell->face(
face)->clear_user_flag()
doesn't clear the user flag in the other distributed meshes?
That's correct. The flag is only cleared
This works!! Thanks.
I am guessing something like:
if(cell_neighbour->is_ghost()==true)
cell->face(neighbour_face_number)->clear_user_flag();
won't clear the user flag everywhere either, because that didn't work.
Right?

Hello everyone!
This is deal.II newsletter #251.
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:
#15151: Allow MappingInfo::reinit_cells() to work on containers
Right, it won't clear it everywhere. You would need to use MPI to clear the
flag on the other processor. If you would do that you would create a huge
amount of messages and your code would be extremely slow.
Best,
Bruno

Hi folks,
I'm trying to use the block_operator technique on Trilinos vectors and
matrices, but I can't quite get it to compile. For simplicity, the relevant
lines of code are:
```
#include
#include
using vec = dealii::LinearAlgebraTrilinos::MPI::Vector;
using block_vec =
I would suggest that you use MeshWorker::mesh_loop() to do this (or
look at the complicated implementation of it).

Kumar,
can you come up with a small example that illustrates the problem? We can't
tell where the error might come from without seeing a (complete) piece of code
and an input mesh.
