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 cell. In addition you can use energy.
Best,
H.

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 only the area has to be refined, which is
cracked. I have seen the second one in step-12 but I could not
find out how can I change the geometry and the crack direction on
it. I took a look at the FAQ, the tutorials and the videos too but
unfortunately could not find the answer which I need. Thank you in
advance for your answer.
Best regards
Reza
