forceModel MeiLift command :h3

[Syntax:]

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

forceModels
(
    MeiLift
);
MeiLiftProps
\{
    velFieldName        "U";
    useSecondOrderTerms;
    treatForceExplicit  switch1;
    verbose             switch2;
    interpolation       switch3;
    scalarViscosity     switch4;
\} :pre

{U} = name of the finite volume fluid velocity field :ulb,l
{useSecondOrderTerms} = (optional, default false) switch to activate second order terms in the lift force model :l
{switch1} = (optional, default false) sub model switch, see "forceSubModel"_forceSubModel.html for details :l
{switch2} = (optional, default false) switch to activate the report of per-particle quantities to the screen :l
{switch3} = (optional, default false) switch to activate tri-linear interpolation of the flow quantities at the particle position :l
{switch4} = (optional, default false) sub model switch, see "forceSubModel"_forceSubModel.html for details :l
:ule

[Examples:]

forceModels
(
    MeiLift
);
MeiLiftProps
\{
    velFieldName        "U";
    useSecondOrderTerms;
    interpolation       true;
    verbose             true;
\} :pre

[Description:]

The force model performs the calculation of forces (e.g. fluid-particle
interaction forces) acting on each DEM particle. The {MeiLift} model calculates
the lift force for each particle based on Loth and Dorgan (2009). In case the
keyword "useSecondOrderTerms" is not specified, this lift force model uses the
expression of McLaughlin (1991, J. Fluid Mech. 224:261-274).
