forceModel surfaceTensionForce command

Syntax

Defined in couplingProperties dictionary.

forceModels
(
    surfaceTensionForce;
);
surfaceTensionForceProps
{
    stfFieldName "surfaceTensionField";
}

  • surfaceTensionField = name of the surface tension force field

Examples

forceModels
(
    surfaceTensionForce;
);
surfaceTensionForceProps
{
    stfFieldName "surfaceTensionForce";
}

Description

The force model calculates the surface tension force acting on each DEM particle based on a pre-calculated surface tension force as V_particle * F^sigma. When used in conjunction with the cfdemSolverMultiphase solver, the surface tension force is calculated with the CSF (continuum surface force) model (see Brackbill et al. (1992): “A continuum method for modeling surface tension”, J. Comput. Phys.).

Restrictions

Has to be used with a multiphase solver that calculates the surface tension force, e.g. cfdemSolverMultiphase.
