dictionary.

forceModels
(
    ArchimedesIB

ArchimedesIBProps
\{
    gravityFieldName      "gravity";
    voidfractionFieldName "voidfraction";
    twoDimensional;

\} :pre

{gravity} = name of the finite volume gravity field :ulb,l
{voidfraction} = name of the finite volume voidfraction field :l
{twoDimensional} = optional keyword for conducting a two dimensional calculation :l
{switch1} = (optional, default false) sub model switch, see "forceSubModel"_forceSubModel.html for details :l
:ule

[Examples:]

forceModels
(
    ArchimedesIB
);
ArchimedesIBProps
\{
    gravityFieldName      "g";
    voidfractionFieldName "voidfractionNext";
\} :pre

[Description:]

The force model performs the calculation of forces (e.g. fluid-particle
interaction forces) acting on each DEM particle. The {ArchimedesIB} model is a
model that calculates the ArchimedesIB' volumetric lift force stemming from
density difference of fluid and particle. This model is especially suited for
resolved CFD-DEM simulations where the particle is represented by immersed
boundary method.

[Restrictions:]

Only for immersed boundary solvers.
