To answer if it really happens when I call compress (), I added a bit of
tracking:

Sean,
Thanks for the wonderfully clear answer. For my function f, I can
basically treat the line integral like a "normal" volume integral,
setting the direction using the delta functions. This would be the right
approach for a distributed adaptive setting as well, no?
Yes. You'd write the i
This is how I setup my sparsity pattern:
if (discretization=="DFEM")
fe = new FE_DGQ (p_order);
else
fe = new FE_Q (p_order);
dof_handler.distribute_dofs (*fe);
locally_owned_dofs = dof_handler.locally_owned_dofs ();
DynamicSparsityPattern dsp (locally_owned_dofs);

And it really happens when you call `compress()`?
The only thing I can think of is that you didn't set up the sparsity
pattern correctly. Can you show us the code that sets up the

Dear All

Thanks for answering!
The warnings come from my code, which is in developing stage!
In the installation I had before,
[-Wunused-variable],[-Wunused-parameter],[-Wunused-but-set-variable] did
not show up. It's a bummer that changing deal.II version will make such a

Dear All,
I am doing a radiation transport problem, which has multiple individual
equations (number determined by the number of directions we input). As the
number of directions is arbitrary, I put the sparsematries are contained in
