cfdemSolverRhoPimple
Description
Transient solver for compressible flow using the flexible PIMPLE (PISO-SIMPLE)
algorithm.
Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.
The code is an evolution of the solver rhoPimpleFoam in OpenFOAM(R) 4.x,
where additional functionality for CFD-DEM coupling is added.

[Description:]
This "forceModel" does not influence the particles or the flow - it calculates the particle momentum-diameter correlation
:c,image(Eqs/pdCorrelation.png)
where delta is the type-specific coarsegraining factor.
This model is sensitive to additionally pulled particle type info, and can either use the type-specific densities from the dict or those pulled from LIGGGHTS.
[Restrictions:]
none.
