[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"_cfdemSolverMultiphase.html
|
|
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}.
