Adding Field Functions

Field functions provide a mechanism by which fields (raw data from the simulation stored in cells and/or on boundaries) may be viewed and defined. User field functions are field functions that you create to access field data. This section illustrates how to create a new field function for post-processing purposes that represents the ratio of absolute pressure to atmospheric pressure.

This entry instructs your new field function to reference the Absolute Pressure field function, and states that the atmospheric pressure value is 101,325.0 Pa.
