8.15.1 Actual Reference Pressure Location

For cases that do not have pressure-related boundary conditions (e.g., pressure inlet, pressure outlet, pressure far-field, etc.), you need to specify the Reference Pressure Location at a point in the problem domain. Internally, ANSYS FLUENT sets the location of the reference pressure at a slightly different nearby location. Thus, the actual location used as the pressure reference is different than that of your input value. To report the actual reference pressure location that ANSYS FLUENT uses, use the following text command:

define $\rightarrow$ operating-conditions $\rightarrow$ used-ref-pressure-location

This text command is available only when the case is initialized and has no pressure-related boundary zones.

Note that reporting the actual reference pressure location is not available through the graphical user interface.
