Detailed Description

Solver module base-class for for 2 immiscible fluids, 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.
