Magnesium Alloy Dislocation Dynamics, CRADA No. TC02199.0
This was a collaborative effort between Lawrence Livermore National Security, LLC as manager and operator of Lawrence Livermore National Laboratory (LLNL) and The Johns Hopkins University to develop a discrete defect dynamics method to predict the behavior of Magnesium polycrystalline alloys undergoing dynamic deformation though coupled slip and twinning building off of the ParaDiS dislocation dynamics code with finite element coupling.

ParaDiS-FEM dislocation dynamics simulation code primer
The ParaDiS code is developed to study bulk systems with periodic boundary conditions. When we try to perform discrete dislocation dynamics simulations for finite systems such as thin films or cylinders, the ParaDiS code must be extended. First, dislocations need to be contained inside the finite simulation box; Second, dislocations inside the finite box experience image stresses due to the free surfaces. We have developed in-house FEM subroutines to couple with the ParaDiS code to deal with free surface related issues in the dislocation dynamics simulations. This primer explains how the coupled code was developed, the main changes from the ParaDiS code, and the functions of the new FEM subroutines.
