<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>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.
