forceModel virtualMassForce command :h3

[Syntax:]

Defined in "couplingProperties"_CFDEMcoupling_dicts.html#couplingProperties
dictionary.

forceModels
(
    virtualMassForce
);
virtualMassForceProps
\{
    velFieldName "U";
    phiFieldName "phi";
    splitUrelCalculation switch1;
    Cadd scalar1;
    treatForceExplicit switch2;
    interpolation switch3;
\} :pre

{U} = name of the finite volume fluid velocity field :ulb,l
{phi} = name of the finite volume flux field :l
{switch1} = (optional, default false) indicator to split calculation of Urel between CFDEM and LIGGGHTS :l
{scalar1} = (optional, default 0.5) virtual mass coefficient :l
{switch2} = (optional, default true) sub model switch, see "forceSubModel"_forceSubModel.html for details :l
{switch3} = (optional, default false) sub model switch, see "forceSubModel"_forceSubModel.html for details :l
:ule

[Examples:]

forceModels
(
    virtualMassForce
);
virtualMassForceProps
\{
    velFieldName "U";
    phiFieldName "phi";
\} :pre

[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.

IMPORTANT NOTE: Model not validated!
