This is a finite element code based in deal.II to simulate crack propagation in elastic and porous media.
- phase field approach for the crack location
- primal-dual active set method for the irreversibility constraint
- novel adaptive mesh refinement technique
This project was originally developed for the two papers mentioned below, but has been extended considerably since then. Please cite these papers if you make use of our work. Thank you!

How to run
You need to install deal.II (see http://www.dealii.org) with external dependencies p4est and Trilinos. Then configure with:
cmake -D DEAL_II_DIR=/your/dealii-installation/ .
and finally run with:
mpirun -n 2 ./cracks parameters_sneddon_2d.prm
The code is published under GPL v2 or newer.
