forceModel_ArchimedesIB command

Syntax

Defined in couplingProperties dictionary.

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

  • gravity = (optional, default “g”) name of the finite volume gravity field

  • voidfraction = (optional, default “voidfraction”) name of the finite volume voidfraction field

  • twoDimensional = optional keyword for conducting a two dimensional calculation

  • switch1 = (optional, default true) 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.
