What is PRISMS-Plasticity?

PRISMS-Plasticity is a Finite Element Method (FEM) code for solving boundary value problems arising in Continuum Plasticity and Crystal Plasticity. It is build on top of the deal.II open source finite element library [http://www.dealii.org]

This code is developed by the PRedictive Integrated Structural Materials Science (PRISMS) Center [http://www.prisms-center.org/] at University of Michigan which is supported by the U.S. Department of Energy (DOE), Office of Basic Energy Sciences, Division of Materials Sciences and Engineering under Award #DE-SC0008637

Installation: Refer to the installation manual in docs/installation manual.pdf for detailed instructions on getting started with using the plasticity code.

you need to compile deal.ii without trilinos package. To do that, if you're using candi, you can turn it off in candi.cfg by commenting that as #PACKAGES="${PACKAGES} once:trilinos". With deal.ii installed and $DEAL_II_DIR setup, the following steps can be followed to download and compile the code.

  1. Clone the PRISMS Plasticity GitHub repo https://github.com/prisms-center/plasticity
  1. Compile the library
  • $ cmake .
  • $ make -j N
  • $ export PLAS_DIR=$PWD
    Here N refers to number of processor cores available, this helps in quicker compilation.
  1. Compile plasticity applications
  • $ cd applications/crystalPlasticity
  • $ cmake .
  • $ make release

Running an example simulation

  • $ cd applications/crystalPlasticity/fcc/simpleTension
    Making results directory
  • $ mkdir results
    Execution (parallel runs):
  • $ mpirun -np nprocs $PLAS_DIR/applications/crystalPlasticity/main prm.in
    [here nprocs denotes the number of processors]

Updates: Since plasticity code is still under active development, regular code and documentation updates are pushed to the upstream repo (https://github.com/prisms-center/plasticity) and we strongly recommend users to synchronize their respective clones/forks at regular intervals or when requested by the developers through the announcements on the mailing list.

Visualization

Output of the primal fields and postprocessed fields is in standard vtk format (parallel:.pvtu, serial:.vtu files) which can be visualized with the following open source applications:

  1. VisIt (https://wci.llnl.gov/simulation/computer-codes/visit/downloads)
  2. Paraview (http://www.paraview.org/download/)

Getting started:

Examples of various boundary value problems are located under the applications/ folder. Easiest way to get started on the code is to run the applications.

Applications are intended to serve as (1) Demonstration of the capabilities of this library, (2) Provide a framework for further development of specialized/advanced applications by users.

Application or code under development/testing is preceded by an underscore.
