momCoupleModel_implicitCouple command¶

Syntax¶

Defined in couplingProperties dictionary.

momCoupleModels
(
    implicitCouple
);
implicitCoupleProps
{
    velFieldName "U";
    granVelFieldName "Us";
    voidfractionFieldName "voidfraction";
    minAlphaP number;
}

U = name of the finite volume fluid velocity field
Us = name of the finite volume granular velocity field
voidfraction = name of the finite volume voidfraction field

number = minimum value for local particle volume fraction to calculate the exchange filed (default SMALL):l

Examples¶

momCoupleModels
(
    implicitCouple
);
implicitCoupleProps
{
    velFieldName "U";
    granVelFieldName "Us";
    voidfractionFieldName "voidfraction";
}

Description¶

The implicitCouple-model is a momCoupleModel model providing an implicit momentum source term for the CFD solver.

Restrictions¶

Only for solvers that include implicit momentum exchange.
