forceModel_virtualMassForce command¶
Syntax¶
Defined in couplingProperties dictionary.
forceModels
(
virtualMassForce
);
virtualMassForceProps
{
velFieldName "U";
phiFieldName "phi";
splitUrelCalculation switch1;
Cadd scalar1;
treatForceExplicit switch2;
treatForceDEM switch3;
interpolation switch4;
UInterpolationType "type1"
DDtUInterpolationType "type2"
};
- U = name of the finite volume fluid velocity field
- phi = name of the finite volume flux field
- switch1 = indicator to split calculation of Urel between CFDEM and LIGGGHTS
- scalar1 = scalar value
- 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
- type1 = (optional, default cellPointFace) interpolation type for U field
- type2 = (optional, default cellPointFace) interpolation type for ddt(U) field
Examples¶
forceModels
(
virtualMassForce
);
virtualMassForceProps
{
velFieldName "U";
}
Description¶
The force model performs the calculation of forces (e.g. fluid-particle interaction forces) acting on each DEM particle. The virtualMassForce model calculates the virtual mass force for each particle.
Restrictions¶
Model not validated!
