This section describes the outputs you can obtain from the Flow module. The following types of data are available for output from the Flow module:

Primary variables are the fundamental variables for a given set of modules and models. They are required as part of the solution.

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.

Property variables are the physical properties for the fluids and solids in the domain. They are required as part of the solution.

Physical property output for the Flow module is automatically activated for selected volumes and boundaries, except point probes, depending on the models that are selected.

Derived variables are engineering data computed from the primary variables. While not required as part of the solution, they can provide valuable information for analysis of the results.

Derived variable output for the Flow module is automatically activated for selected volumes and boundaries, (other than point probes) depending on the models that are selected.

Boundary variables are data associated with a Boundary. You can integrate primary and derived variables over a selected Boundary The quantities available for output for the boundary for the Flow module depend on the boundary type.

You can activate the required output for a selected boundary under the Flow module in the Properties panel.

Integrated output are quantities that are integrated over a Boundary, Interface, or Volume.
