- In this video, you will learn the basics of User Defined Functions (UDF) and how to write a UDF code, what each statement means inside the code file, and how to interpret it and use it in ANSYS FLUENT Software.

Thank you for your systematic explanation! This video helps a lot.
hello my teacher
I will have a pressure study on UDF time dependent and can you send me an example of this on a three-dimensional pipe.
thank you teacher
thank you, saved me hours
Very nice explanation. please make a video on the pulsatile flow of blood.
Very good tutorial, please continue
Hello Mr. Kouta,
I am getting the following error:
Error: C:/Users/kombe/AppData/Local/Temp/Vtrial.c.13720.3.c: line 12: non-integer subscript expression: double.
On this line: F_PROFILE(t,thread,position) = (15*t)
Do you know why??
Did you try adding the point between 15 and *? - (15.*t)
Hello Ahmad, thanks for this amazing tutorial. I'm working an a variable inlet temperature inside a pipe depending on the time steps.
I want the temperature profile to be 27°C between 0 and 600 min and 29,5°C between 1700 and 2330 min, otherwise I wand a constant temperature profile at 31°C.
How can I add these modifications to your UDF code?
Kind regards
Great video!
very helpful video. please make a video on how to apply a non uniform (gaussian) heat flux on wall of tube
sir can you please tell me how i can make the UDF for a data file which i want to give as a heat source on the surface of wall. Please revert sir.
Thank you Ahmad
great one! thanks a lot
hi, if my problem is steady state i have to change "realt=CURRENT_TIME;" ??
How can we add a profile equation at the outlet?
Hi Sir,
thanks so much,
I'm wondering to ask the Nusselt number and temperature gradient UDFs
Heyy.I need suggestions and help to write for 3d pipe flow udf coding.
TIA
Hello, can you share the note of UDF parameter? Thank you
Error: floating point exception
Error Object: #f
What does it mean ?
This error usually occurs when some number is divided by zero and causes the simulation to stop. Check your parameters. Also, there may be a problem with the mesh. So try improving the mesh too.
@@AhmadKoutathanks for your advice I will try 😊
