+
+[Description:]
+
+"cfdemSolverIBContinuousForcing" is a coupled CFD-DEM solver using CFDEMcoupling,
+an open-source parallel coupled CFD-DEM framework, for calculating the dynamics
+between immersed bodies and the surrounding fluid. Being an implementation of a
+continuous forcing immersed boundary method it allows tackling problems where
+the body diameter exceeds the maximal size of a fluid cell.
+
+<!-- HTML_ONLY -->
+Using the toolbox of OpenFOAM&reg;(*) the governing equations of the fluid are
+computed and the corrections of velocity and pressure field with respect to the
+body-movement information, gained from LIGGGHTS, are incorporated.

+
+[Use:]
+
+The solver is realized within the open-source framework CFDEMcoupling. Just as
+for the unresolved CFD-DEM solver cfdemSolverPiso the file
+CFD/constant/couplingProperties contains information about the settings for the
+different models. While IOmodel, DataExchangeModel etc. are applicable for all
+CFDEMcoupling-solvers, special locate-, force- and void fraction models were
+designed for this solver:
