Hey everyone,
I am trying to simulate a multiphase flow model in a heat pipe using VOF and udf method. I opened fluent via Visual studio 2013 x64 cross command prompt so as to fix the 'nmake' error and I have compiled my UDF successfully.And after loading the compiled udf, when I select 'user-defined' option in Define -> Phase -> Interaction -> mass, I get the error message:"No user defined have been loaded". I also set the Linearized mass transfer to "no" using "solve -> set -> expert" command from TUI, but I still get the error.
When I googled it, I found that there is problem with "loading udfs" in Ansys16 cracked version, so my question is: is there a fix for this issue for the cracked version, or is there any other version of ansys that doesn't result in this kind of error?
P.S: I have also tried to load udf using the Define -> user-defined -> functions ->intrepreted. But it gives me a error in a line that is beyond the last line of my sourceterm. The error it throws is "C:\\Users\\XXXX src\\sourceterm.c: line 65: label "store_vof_norm" not found (pc=58)".
Any help is appreciated.
Cheers,

Can you help me in multiphase evaporation - condensation, please? 😅
