Hi all,

Actually, I need to help from everybody. I am facing one problem in UDFs of Fluent software. Because velocity at inlet condition varies time function as shown in attached firgure, I still did not described this function by using UDFs in Fluent.
Actually, I can describe time function by data which stored in file (format **.txt), and put this data in my code. However, I did not know how to defined time solution when it running.
Anybody help me to solve this problem?
Thanks so much.

If you send me the data or post it here, I'll try and get a UDF that will work.

Hi trantoan2008,

Did you solve your time series problem (velocity varies with time)? I am dealing with the same problem. Have you any udf for this problem?

Thank you in advance,
NV
