Dear Reza,
there is also a deal.II gitHub "tutorial" on phase-field fracture,
which exactly addresses your questions:

Hi
1) You can use UCD or Abaqus mesh format as input.
2) The best choice in mesh refinement is phase field variable. I have used
phase field as control variable. Loop over cells and check the phase field
variable in the cells. If phase field variable was greater than a limit
then refine the cel
Hi,
you can read meshes from various formats,
see https://www.dealii.org/developer/doxygen/deal.II/classGridIn.html
W.r.t. adaptive refinement, this is a big area of research and you need to
do a literature review to see how people do it in your field. Generally, it
boils down to (i) error est
Dear all,
currently I do my master thesis and firstly I have to do adaptive mesh
refinement for a brittle fracture in 2D using a phase-field approach but
with my own geometry. I would like to ask you how can I input my geometry
in dealii-8.4.1, which version I use and how can I command that onl
Thanks Bruno! The reason that I didn't use material_id is that I didn't
know it:) I will take a look at step-28 to learn it.
Best,
Chenchen

Chenchen,
is there a reason why you can't use material_id? If you can't, you could
use user_flag or user_pointer

Hi all,
I am working on highly heterogeneous materials (see the simple cartoon in
the following). It is composed of two kinds of constituents, A (blue) and B
(white). The traditional methods is to check the position of the cell to
see whether it belongs to phase A or B. Even though I have all t
p.s. if the issue is resolved, please mark it as such ;-)
