    interpolation   switch4;
};

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

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

• twoDimensional = optional keyword for conducting a two dimensional calculation

• switch1 = (optional, default false) can be used to suppress the output of the probe model

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

• switch3 = (optional, default false) sub model switch, see forceSubModel for details

• switch4 = (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.

If the particleShapeType multisphere is selected, caluclations are performed for multisphere particles. In this operation mode additional input for DHc or area per particle type may be required. Without this input the multisphere variant may fail.

Restrictions

none.
