forceModel_virtualMassForce command

Syntax

Defined in couplingProperties dictionary.

forceModels
(
    virtualMassForce
);
virtualMassForceProps
{
    velFieldName "U";
    phiFieldName "phi";
    splitUrelCalculation switch1;
    Cadd scalar1;
    treatForceExplicit switch2;
    treatForceDEM switch3;
    interpolation switch4;
    UInterpolationType "type1"
    DDtUInterpolationType "type2"
};

  • U = (optional, default “U”) name of the finite volume fluid velocity field

  • phi = name of the finite volume flux field

  • switch1 = indicator to split calculation of Urel between CFDEM and LIGGGHTS

  • scalar1 = scalar value

  • switch2 = (optional, default true) sub model switch, see forceSubModel for details

  • switch3 = (optional, default false) sub model switch, see forceSubModel for details

  • switch4 = (optional, default false) sub model switch, see forceSubModel for details

  • type1 = (optional, default cellPointFace) interpolation type for U field

  • type2 = (optional, default cellPointFace) interpolation type for ddt(U) field

Examples

forceModels
(
    virtualMassForce
);
virtualMassForceProps
{
    velFieldName "U";
}

Description

The force model performs the calculation of forces (e.g. fluid-particle interaction forces) acting on each DEM particle. The virtualMassForce model calculates the virtual mass force for each particle.

Restrictions

Model not validated!
