Wrong units of user defined field function
 

Fluent doesn't seem to mind custom field functions which use units (dimensions) loosely, for example taking log of a temperature etc.:

The result is displayed as a numerical value and is left for the user to interpret. So far so good.
However, exporting this field to .cdat using the File - Export - During Calculation CDAT for CFD-Post and Ensight, the field function values are all messed up. I suspect Fluent attempts to account for the dimension operations or something similar? Is there a way to just export the field without units to CFD Post? Thanks.
