Hi,
Sorry for the spam.
I tried to search but did not find an implementation of shell elements in
deal.II. Since this is a commonly used element, I'd like to make sure that
it's not me missing it. Could you please help confirm?
Best,
Shawn

Second update (sorry for so many updates)
I changed my strategy to use set(r, c, v) function to set the values so
that I can use the const iterators. also called compress after every add:
for (auto r = Abs_A_matrix->block(0, 0).local_range().first;
r < Abs_A_matrix->block(0, 0).local_range().seco
An update:
I tried to use a iteration below to iterate over local entries: (The reason
I use local_range() for only (0, 0) block and iterator for the entire block
matrix is because I only need the block(0, 0), and sparse matrix class does
not have a non-const iterator, I have to call the local
Following this, note that using the stress as a tensor function produced
the same results/problems (same errors too as doing it with component_i)
but wouldn't have thought that would have made a difference anyway...

Hi Wolfgang,
I believe the formula is correct. the cubic term comes from p=z^3 being the
pressure manufactured solution. so in (pI-2e) you get a z^3 term and indeed
a linear term in the 2e portion.
The code commpiles and the error analysis is correct with Dirichlet
conditions on the top and bo
Hi,
I'm using PETScWrapper to parallelize my code. In my preconditioner for the
GMRES solver, there is one step that requires a matrix copied from the
system matrix, and set all the elements to be the absolute value. It was
fine in serial because I can iterator over all the entries simply using
