| Foam::solvers::twoPhaseVoFSolver | |
| Description | |
| Solver module base-class for 2 immiscible fluids using a VOF (volume | |
| of fluid) phase-fraction based interface capturing approach, with optional | |
| mesh motion and mesh topology changes including adaptive re-meshing. | |
| The momentum and other fluid properties are of the "mixture" and a single | |
| momentum equation is solved. | |
| Either mixture or two-phase transport modelling may be selected. In the | |
| mixture approach a single laminar, RAS or LES model is selected to model the | |
| momentum stress. In the Euler-Euler two-phase approach separate laminar, | |
| RAS or LES selected models are selected for each of the phases. | |
| Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and | |
| pseudo-transient and steady simulations. | |
| Optional fvModels and fvConstraints are provided to enhance the simulation | |
| in many ways including adding various sources, Lagrangian | |
| particles, surface film etc. and constraining or limiting the solution. | |
