-Description
-    This code is designed to realize coupled CFD-DEM simulations using LIGGGHTS
-    and OpenFOAM. Note: this code is not part of OpenFOAM (see DISCLAIMER).
-\*---------------------------------------------------------------------------*/
-
-
-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(R)(*). The CFDEMcoupling toolbox allows to expand 
-standard CFD solvers of OpenFOAM(R)(*) 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"_lws 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 file structure:
-
-- "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 CFDEMcoupling
-- "tutorials" directory including basic tutorial cases showing the functionality
-
-
-
-Details on installation are given on the "www.cfdem.com"
-
-The functionality of this CFD-DEM framwork is described via "tutorial cases" showing 
-how to use different solvers and models.
-
-CFDEMcoupling stands for Computational Fluid Dynamics (CFD) -
-Discrete Element Method (DEM) coupling.
-
-CFDEMcoupling is an open-source code, distributed freely under the terms of the 
-GNU Public License (GPL).
-
-Core development of CFDEMcoupling is done by 
-Christoph Goniva and Christoph Kloss, both at DCS Computing GmbH, 2012
