| Foam::solvers::multiphaseVoFSolver | |
| Description | |
| Base solver module for the solution of multiple 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. | |
| Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and | |
| pseudo-transient and steady simulations. | |
