pfm-cracks: A parallel-adaptive framework for phase-field fracture propagation

This is a finite element code based on the finite element library deal.II to simulate crack propagation in elastic and porous media.

Features:

  • phase field approach for the crack location
  • support for 2d and 3d computations
  • primal-dual active set method for the irreversibility constraint
  • novel adaptive mesh refinement technique

This project was originally developed for the papers mentioned below, but has been extended considerably since then. Please cite these papers if you make use of our work. Thank you!

The original code versions are available as separate branches in this repository:

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/ .

Compile with:

  make

and finally run with:

  mpirun -n 2 ./cracks parameters_sneddon_2d.prm

Notes

The code is published under GPL v2 or newer.
