Dear Sir I would like to write a UDF for a pressure inlet profile in an unsteady-state problem. I mean the pressure varies with time and also the pressure curve equation changes 2 times in the period. I have studied the UDF manual, but there was no UDF about time varying problem. Would you please help me? Thanks.

There is a tutorial problem with time varying velocity... please see if that helps...

Google search could also provide you some information...

Dear AJ Thanks for your great favor. But I have more questions: 1. May I use that for 3D models? 2. How can I change the equation during time? (Maybe I should use some if ... else statements)
