<UL><LI><I>coarseGrainingFactors</I> = list of coarse graining factors by type, separated by whitespace, optional

<P><B>Description:</B>
</P>
<P>This "forceModel" does not influence the particles or the flow - it calculates the particle momentum-diameter correlation

<P>where delta is the type-specific coarsegraining factor.
</P>
<P>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.

<P><B>Restrictions:</B>
