I have built and loaded a UDF into fluent but when i try to initialize the solution, it does not work.

I get some outputs from my UDF and then an error message:

INIT Total column Volume 0.001528 (m3)
INIT Total inlet Area 0.002545 (m2)
INIT Total outlet Area 0.002545 (m2)
INIT Initial column temperature 293.000000 (K)
INIT Initial column density (kg/m3) 1.16516
INIT Average CO2 fraction in column 0.00000

The fl process could not be started.

I am not sure what could be causing the message "the fl proccess could not be started". Unfortunately, I did not write the UDF but if you need to see parts of it I can share that with you. Thanks for your help!
