the problem is about the UDFs. I have tried these UDFs on fluent 14 and fluent 15.07 in two different occasions.
I have run this case and data in fluent 14 for many many iterations.
I also run this case in fluent 15.07 from the beginning ( I mean init)
so I am sure that UDF are fine.
also I am sure that the problem is with the UDFs. because when I diactiveate them there will be no errors.
please help
