forceModel_viscForce command :h3

[Syntax:]

Defined in couplingProperties dictionary.

forceModels
(
    viscForce;
);
viscForceProps
\{
    velocityFieldName "U";
    interpolation "switch";
\}; :pre

{U} = name of the finite volume fluid velocity field :ulb,l
{switch} = flag to use interpolated stress values (normally off) :l
:ule

[Examples:]

forceModels
(
    viscForce;
);
viscForceProps
\{
    velocityFieldName "U";
\} :pre

[Description:]

The force model performs the calculation of forces (e.g. fluid-particle interaction forces) acting on each DEM particle. The viscForce model calculates the particle based viscous force, -(grad(tau)) * Vparticle (see Zhou et al. (2010): "Discrete particle simulation of particle-fluid flow: model formulations and their applicability", JFM).

[Restrictions:]

none.
