Detailed Description

Solver module for the solution of multiple compressible, isothermal 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.

A mixture approach for momentum transport is provided in which a single laminar, RAS or LES model is selected to model the momentum stress.

Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and pseudo-transient and steady simulations.
