forceModel pdCorrelation¶

Syntax¶

Defined in couplingProperties dictionary.

forceModels
(
    pdCorrelation
);
pdCorrelationProps
{
    coarseGrainingFactors
    (
        X Y Z
    );
    particleDensities
    (
        A B C
    );
    runOnWriteOnly true;
}

• coarseGrainingFactors = list of coarse graining factors by type, separated by whitespace, optional

• particleDensities = list of particle densities by type, separated by whitespace, optional

• runOnWriteOnly = switch if this should be executed on write, optional (default: false - execute every coupling step).

Description¶

This “forceModel” does not influence the particles or the flow - it calculates the particle momentum-diameter correlation

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
