UDF error
 

Hello everyone
I have made a udf for backlow temperature in pressure outlet.
There are no errors in the code after interpreting.
But when I initialise my solution following error comes:

"FLUENT received fatal signal (ACCESS_VIOLATION)
1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor."

I am using a cracked version of ansys so someone who is familiar with this error please help me.
Any help would be appreciated.

Dear administrators,

Can't you filter all messages with "fluent", "udf", "gambit" etc and move them to the fluent forum?
