DOes any one have an example of the udf where i can have a guide to follow on. THanks cos i am really terrible in those C-programming stuff... thanks a lot once again

Hi,

Learning the basics of C used in Fluent UDFs will not take more than a couple hours. If you follow the UDF manual it will give you the basic concepts and a google on "c tutorial" will give you the rest. Good Luck.
