Output Variables
This section describes the outputs you can obtain from the Multiphase module. The following types of data are available for output from the Multiphase module:
Primary Variables
Property Variables
Integrated Quantities
Output of Primary Variables
Primary variables are the fundamental variables for a given set of modules and models. They are required as part of the solution.

At a Point and in the GUI Display Window
Primary variables are automatically activated for selected geometric entities such as boundaries, derived surfaces, interfaces, streamlines, particles, or volumes depending on the modules and models that are selected.
Output of Property Variables
Property variables are the physical properties for the fluids and solids in the domain. They are required as part of the solution.
