forceModel Archimedes command

Syntax

Defined in couplingProperties dictionary.

forceModels
(
    Archimedes
);
ArchimedesProps
{
    gravityFieldName   "gravity";
    treatForceExplicit switch1;
    treatForceDEM      switch2;
}

  • gravity = name of the finite volume gravity field

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

  • switch2 = (optional, default false) sub model switch, see forceSubModel for details

Examples

forceModels
(
    Archimedes
);
ArchimedesProps
{
    gravityFieldName "g";
}

Description

The force model performs the calculation of forces (e.g. fluid-particle interaction forces) acting on each DEM particle. The Archimedes model is a model that calculates the Archimedes’ volumetric lift force stemming from density difference of fluid and particle.
