dictionary.

{coarseGrainingFactors} = list of coarse graining factors by type, separated by whitespace, optional :ulb,l
{particleDensities} = list of particle densities by type, separated by whitespace, optional :l
{runOnWriteOnly} = switch if this should be executed on write, optional (default: false - execute every coupling step). :l

[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 coarse-graining factor.

This model is sensitive to additionally pulled particle type info, and can
either use the type-specific densities from the dictionary or those pulled from
LIGGGHTS.

[Restrictions:]

none
