Description

This code provides models and solvers to realize coupled CFD-DEM simulations using LIGGGHTS and OpenFOAM® technology.

Note:

This code is not part of OpenFOAM®.
This offering is not approved or endorsed by OpenCFD Limited, the producer of the OpenFOAM® software and owner of the OPENFOAM® and OpenCFD® trade marks.

CFDEM® coupling provides an open source parallel coupled CFD-DEM framework combining the strengths of LIGGGHTS® DEM code and the Open Source CFD package OpenFOAM®(). The CFDEM®coupling toolbox allows to expand standard CFD solvers of OpenFOAM®() to include a coupling to the DEM code LIGGGHTS®. In this toolbox the particle representation within the CFD solver is organized by "cloud" classes. Key functionalities are organised in sub-models (e.g. force models, data exchange models, etc.), which can easily be selected and combined by dictionary settings.

The coupled solvers run fully parallel on distributed-memory clusters.

Features are:

  • its modular approach allows users to easily implement new models
  • its MPI parallelization enables to use it for large scale problems
  • the "forum" (www.cfdem.com) on CFD-DEM gives the possibility to exchange with other users / developers
  • the use of GIT allows to easily update to the latest version
  • basic documentation is provided

The CFDEM®coupling distribution includes the following files and directories:

  • "README.md" file (this file)
  • "COPYING" file the GNU General Public License (GPL)
  • "DISCLAIMER" file
  • "src" directory including the source files of the coupling toolbox and models
  • "applications" directory including the solver files for coupled CFD-DEM simulations
  • "doc" directory including the documentation of CFDEM®coupling
  • "tutorials" directory including basic tutorial cases showing the functionality

Details on installation are given on the "www.cfdem.com" website.

The functionality of this CFD-DEM framwork is described via "tutorial cases" showing how to use different solvers and models.

CFDEM®coupling stands for Computational Fluid Dynamics (CFD) - Discrete Element Method (DEM) coupling.
