FLUENT Parallel Problem (UDF)

soheilr · June 16, 2016, 03:49

Hi,
I am trying to use parallel for my UDF. But I faced this error.
I have checked different thing: 1. Using both ANSYS v14.0 and v16.2 2. Uninstall and reinstall ansys and also intel mpi. But unfortunately nothing happened.
I am new in UDF and need help about explaining and solving this error!

any advice will be appreciated.
King Regards.

This error occurs when the process is trying to access a variable that isn't available. What is your UDF code and did it work in serial?
