+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
