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.
Others have already commented on how to refine the mesh based on computed
criteria. A possibly simpler approach would be to refine by hand certain
cells, if you know where the cracked region is (or all cells that are within a
certain distance of the crack). This is what is done in step-1, for example.
