forceModel ArchimedesIB command¶

Syntax¶

Defined in couplingProperties dictionary.

forceModels
(
    ArchimedesIB
);
ArchimedesIBProps
{
    gravityFieldName      "gravity";
    voidfractionFieldName "voidfraction";
    twoDimensional;
    treatForceExplicit    switch1;
}

• gravity = name of the finite volume gravity field

• voidfraction = name of the finite volume void fraction field

• twoDimensional = optional keyword for conducting a two dimensional calculation

• switch1 = (optional, default false) sub model switch, see forceSubModel for details

Examples¶

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

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.
