+CFDEMcoupling provides an open-source parallel coupled CFD-DEM framework
 combining the strengths of the "LIGGGHTS"_lig DEM code and the Open Source CFD
 package "OpenFOAM(R)(*)"_of. The CFDEMcoupling toolbox allows to expand standard
 CFD solvers of "OpenFOAM(R)(*)"_of to include a coupling to the DEM code
