MPPICInterFoam
|
|
|
|
Description
|
|
Solver for two incompressible, isothermal immiscible fluids using a VOF
|
|
(volume of fluid) phase-fraction based interface capturing approach.
|
|
The momentum and other fluid properties are of the "mixture" and a single
|
|
momentum equation is solved.
|
|
|
|
It includes MRF and an MPPIC cloud.
|
|
|
|
Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.
