Hi,
I tried to compile the master branch (commit f5375c1) on my system without
any MPI or Trilinos or other dependencies. I received an error when
compiling the function compute_bounding_box inside
source/grid/grid_tools_cache.cc. It complains that
IteratorFilters::LocallyOwnedCell is not deri
Thank you for your help, I am trying to use constraintmatrix now!

Hello everyone!
This is deal.II newsletter #69.
It automatically reports recently merged features and discussions about the
deal.II finite element library.

Chen,
The AffineConstraints class is not included in any release yet. Previously,
this class was called ConstraintMatrix
(https://www.dealii.org/9.0.1/doxygen/deal.II/classConstraintMatrix.html).
The functionality is the same but it is not templated.
Best,
Daniel

Dear Chen,
In deal.II version 9.0, affine constraints are applied using the
ConstraintMatrix class (deal.II/lac/constraint_matrix.h). This class and header
have been deprecated in the developer version, so if you’re using the developer
version the ConstraintMatrix is typedef’d to AffineConstrai
Maxi,
that is covered in the FAQ

Hello, developers, I am trying to add boundary conditions to my FESystems,
there is a RT finite element. I want to constrain it boundary conditions to
zero with affinestraints,
However, when I use deal.ii 9.0.1 to complie my .cc file, I found that the
header file has been removed.
Is the heade
Eugeniy,
my first guess would be that you are setting boundary conditions
inadequately and that this gives you a singular matrix.
What happens if you apply homogeneous Dirichlet boundary conditions for the
velocity everywhere?

For checking the correctness of my calculations, I use manufactured
solutions (similar to step-7). Now I was wondering if it is possible to
create a vector containing the correct solution which can be printed
together with the calculated solution, for example in vtu-files? I have a
function con
Dear Jean-Paul,
I have the same error with increased max_iterations value:
n_of_refines = 2

in the last step was 44.4628.
