24.2.4 Defining the Phases

To define the phases (including their material properties) and any interphase interaction (e.g., surface tension and wall adhesion for the VOF model, slip velocity for the mixture model, drag functions for the mixture and the Eulerian models), you will use the Phases task page (Figure  24.2.2).

Phases

Figure 24.2.2: The Phases Task Page

Each item in the Phases list in this task page is one of two types: a Primary-Phase indicates that the selected item is the primary phase, and Secondary-Phase indicates that the selected item is a secondary phase. To specify any interaction between the phases, click the Interaction... button.

Instructions for defining the phases and interaction are provided in Sections  24.3.4, 24.4.1, and 24.5.2 for the VOF, mixture, and Eulerian models, respectively.
