Integrating data from UDF to Fluent

Hello,
I am currently using a UDF to simulate flow through a heat pipe. The UDF uses an initialization function to set the initial temperature, pressure, and mass flow of the heat pipe. I have been able to compile, hook the functions, and run the simulation with no error messages. However, the source terms (for momentum and mass) and my operating pressure which varies with time do not seem to be directly linked to Fluent. The resulting velocity profile is completely incorrect even though it is being formulated properly in the UDF. There is no difference in the velocity profile when I remove the source terms
How can I ensure that Fluent uses the data from my UDF? Any help with this issue or even a better understanding of how data is passed from the UDF to Fluent would be appreciated.
