31. Field Function Definitions

You must select flow variables for a number of tasks in ANSYS FLUENT. The values are computed and placed in temporary memory that is allocated for storing the results for each cell. For example, the Compute command associated with a dialog box that contains the field variable drop-down list calculates the values of the selected function and places them into temporary storage.

Sections  31.1 and 31.2 provide some general information related to the field variables. In Section  31.3, the variables are listed by category in Tables  31.3.1- 31.3.14. These tables will also indicate when each variable will be available. Section  31.4 contains an alphabetical listing of the variables along with their definitions. All variables appear as they would in the variable selection drop-down lists that are contained in many of the ANSYS FLUENT dialog boxes. Section  31.5 explains how you can calculate your own field function.
