momCoupleModel implicitCouple command

Syntax

Defined in couplingProperties dictionary.

momCoupleModels
(
    implicitCouple
);
implicitCoupleProps
{
    velFieldName          "U";
    granVelFieldName      "Us";
    voidfractionFieldName "voidfraction";
    KslLimit              scalar1;
    minAlphaP             scalar2;
}

  • U = name of the finite volume fluid velocity field

  • Us = name of the finite volume granular velocity field

  • voidfraction = name of the finite volume void fraction field

  • scalar1 = (optional, default 1e10) limit implicit momentum exchange field

  • scalar2 = (optional, default SMALL) minimum value for local particle volume fraction to calculate the exchange field

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.
