Dear all,
I wrote a simple UDF for a transient simulation. The mass flow inlet changes with respect to time :

#include "udf.h"
 
 DEFINE_PROFILE(inlet_mf,th,i)
 {
   face_t f;
   real t = CURRENT_TIME;
   begin_f_loop(f,th)
     {
       if(t <= 50)
          F_PROFILE(f,th,i) = -1E-08*pow(t,5) + 1E-06*pow(t,4) - 6E-05*pow(t,3) + 0.001*pow(t,2) - 0.014*t + 0.062;
              else
          F_PROFILE(f,th,i) = 0;
     }
    end_f_loop(f,th);
 }

The UDF is working correctly in my machine, when I transfer my case file with the UDF on a cluster, the following error is brought up :

Error: chip-exec: function "inlet_mf" not found
Error: chip-exec: function "inlet_mf" not found
Error: chip-exec: function "inlet_mf" not found
Error: chip-exec: function "inlet_mf" not found
Error: chip-exec: function "inlet_mf" not found

I could not find a solution for my this error, note that the case file and the UDF source are located on the same folder, I also tried command like dos2unix. I am running out of option...
Thanks in advance,

Hi!
did you read the dat file before this error appears?
If so, read the dat file after compiling/interpreting.

Hi, thanks for your reply,
I interpreted the UDF on my machine, then I saved the case and data, and I transfered everything to the cluster. So what I do is just reading the case and data without interpretation. That being said, I could solve my problem, the issue disappeared when i change from PCMPI to MPI when loading FLUENT, I could not understand why, probably a bug between gcc and PCMPI
Thanks again,
