Selecting a VOF Multi-Phase Simulation

In the Physics Model Selection dialog, specify the material model as a multi-phase fluid by selecting Multi-Phase Mixture in the Material group.

Select the Implicit Unsteady solver option from the Time group.

Make an appropriate selection from the Viscous Regime group. The Physics Model Selection dialog will then look as shown below.

Make an appropriate selection from the Optional Physics models group:

Select Gravity if gravity forces significantly influence the solution.

Select Surface Tension if surface tension forces significantly influence the solution.

Select Segregated Multi-Phase Temperature if thermal effects are to be included in your simulation.

In the Phase Change group, select Cavitation if cavitation is expected to occur.
