CFDEM®coupling stands for Computational Fluid Dynamics (CFD) - Discrete Element Method (DEM) coupling. It combines the open source packages OpenFOAM® (CFD) and LIGGGHTS® (DEM) to simulate particle-laden flows. CFDEM®coupling is part of the [CFDEM®project](https://www.cfdem.com).

Transient solver for incompressible flow.
Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.
The code is an evolution of the solver pimpleFoam in OpenFOAM(R) 6.0,
where additional functionality for CFD-DEM coupling is added.

[Description:]
As discussed in "gravityEff"_otherForceModel_gravityEff.html, in case of
simulating periodic boxes, it is necessary to have a gravitational source term.
Since that force is added to the gas momentum equation, we need to add the same
force excluding the effect of the gravitational force on the particles
(the gravitational force on the particles is already available on the LIGGGHTS side)
to drive the particles.
This force model performs the calculation of the following force acting on each
DEM particle,

[Description:]
An effective gravitational source term, {gravityEff}, that is necessery to drive
the flow only incase of periodic box simulations.
This source term is added to the momentum equation.
In case of simulating periodic boxes and assuming "homogeneous no-flow condition"
we will have:
:c,image(Eqs/otherForceModels_gravityEff_pic1.jpg)
This equation depicts that in "no-flow condition" static pressure gradient balances the mixture weight.
Therefore, to derive the flow in periodic box simulations, a dynamic pressure gradient is defined as
:c,image(Eqs/otherForceModels_gravityEff_pic2.jpg)
If one replaces the static pressure gradient of the fluid momentum equation with
:c,image(Eqs/otherForceModels_gravityEff_pic3.jpg)
the fluid momentum equation solved in case of periodic box simulations will be
:c,image(Eqs/otherForceModels_gravityEff_pic4.jpg)
The {gravityEff} source term is the third term on the RHS of the momentum equation.
Note that the gravitational body force of the fluid momentum equation is considered
with this source term.
In the basic implementation of {gravityEff}, first we calculate the density of
the mixture and then the source term is calculated based on the third term on the
RHS of the momentum equation.
