Behrooz,
Can you elaborate some more on what you are trying to achieve?
The (pseudo-)code you posted looks OK apart from vertices being declared in
the innermost loop.
You probably want it to be outside the loop over the vertices of a face.
The API for Point can be found at
Hello everyone,
I was just curious if anyone had any suggestions for the above 'const'
qualifier problem I have stated above?
Thanks!

SparseMatrix has no operator+, so this will not work.

Dear Daniel,
Thanks very much for your reply. Actually what I want to do is very simple.
Consider that the above code gives me 3 nodal indices as: 1, 4 and 5.
First, I need to be able to cast them into a set or vector. We can call it
set1.
Then assume that I have another set, e.g. set2, which
Hello everyone,
We are using PRISMS-PF, a phase field framework finite element built upon
the deal.II library (with the MPI and p4est) dependencies.
The code uses the deal.II DataOut class (see code snippet at the end of the
email) to output simulation results into vtu files at certain time

Hi everyone,
I am trying to cast extracted vertex_indices into a set (or vector). Before
that it is needed to make a pair of those indices (just doubling) and to
cast the pairs into a set for further manipulations.
I get the vertex information mainly through following lines of code:
for
