By allowing the degradation along the interfaces, one can better capture the localization, which is often intergranular in polycrystalline materials. The cohesive zone model is simple to implement for non-moving interfaces, once we have access to the 1D elements on the interfaces.
[ ] Prepare the med module to be able to extract edges and edge groups from a .med file.
[ ] Create a function/class in the simulation module (not in the geometry module to keep it uncoupled) that will manage the whole cohesive zone insertion.
[ ] Create a wrapper class for Phon in simulation (if it proves to be a general solution, I can still refactor it later). Going through and understand everything in Phon would take too much time to worth it for now. Rather create a function/class that wraps it. That wrapper should contain a converter to create Mesh object, then to call the create_cohesive_elements function, and finally convert it back to my format. I should not use Phon's capability to write to an input file because it deletes important information, such as material definitions. Some links to start with:

Workflow
The following tasks need to be done:
