forceModel_gradPForce command :h3
[Syntax:]
Defined in couplingProperties dictionary.
forceModels
(
gradPForce;
);
gradPForceProps
\{
pFieldName "pressure";
densityFieldName "density";
velocityFieldName "U";
interpolation;
\}; :pre
{pressure} = name of the finite volume fluid pressure field :ulb,l
{density} = name of the finite volume gravity field :l
{U} = name of the finite volume fluid velocity field :l
{interpolation} = flag to use interolate interpolated pressure values (normally off) :l
:ule
[Examples:]
forceModels
(
gradPForce;
);
gradPForceProps
\{
pFieldName "p";
densityFieldName "rho";
velocityFieldName "U";
interpolation;
\} :pre
[Description:]
The force model performs the calculation of forces (e.g. fluid-particle interaction forces) acting on each DEM particle. The gradPForce model is a model that calculates the particle based pressure gradient force -(grad(p)) * Vparticle (see Zhou et al. (2010): "Discrete particle simulation of particle-fluid flow: model formulations and their applicability" ,JFM).
[Restrictions:]
none.
