  • 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!
