whass34 is on a distinguished road
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
INIT Average N2 fraction in column 1.00000
INIT Inlet N2 (kg) 0.0000000000e+00
INIT Inlet CO2 (kg) 0.0000000000e+00
INIT N2 inside column(kg) 1.7801857116e-03
INIT CO2 inside column(kg) 0.0000000000e+00
INIT Outlet N2 (kg) 0.0000000000e+00
INIT Outlet CO2 (kg) 0.0000000000e+00
INIT Adsorbed CO2-olet (kg) -0.0000000000e+00
INIT Adsorbed CO2-cell (kg) 0.0000000000e+00
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!
