The extended version of CFDEM®coupling is constantly developed and maintained by DCS Computing GmbH - you can find more information here

This repository contains older, publicly available versions of CFDEM®coupling (referred to as "CFDEM®coupling-PUBLIC") and will not be updated in the foreseeable future.

CFDEM®coupling-PUBLIC is compatible with LIGGGHTS-PUBLIC.

The extended version of CFDEM®coupling is compatible with the DEM software Aspherix®, the "successor" of LIGGGHTS® developed and distributed by DCS Computing GmbH, Linz, Austria.

CFDEM®coupling-PUBLIC

CFDEM®coupling-PUBLIC is an Open Source coupled CFD-DEM framework combining the strengths of LIGGGHTS® DEM code and the Open Source CFD package OpenFOAM® ¹. CFDEM®coupling stands for Computational Fluid Dynamics (CFD) - Discrete Element Method (DEM) coupling.

LIGGGHTS® and CFDEM® are registered trade marks of DCS Computing GmbH, the producer of the LIGGGHTS® software and the CFDEM®coupling software; see http://www.cfdem.com/terms-trademark-policy for details.

CFDEM®coupling-PUBLIC is open-source, distributed under the terms of the GNU Public License, version 3 or later. CFDEM®coupling-PUBLIC is part of CFDEM®project: www.liggghts.com | www.cfdem.com. Core developer and main author: Christoph Goniva, christoph.goniva@dcs-computing.com

Features

• Modular approach that allows users to easily implement new models
• MPI parallelization that 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

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.
