FLUENT Parallel Problem (UDF)
 

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.

The fl process could not be started.

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?
