👨🏻‍💻Introduction to UDF Coding with 2D Pipe Flow Simulation Tutorial

[@fitorisqulah1490]

Thank you for your systematic explanation! This video helps a lot.

[@asifraj321]

Very nice explanation. please make a video on the pulsatile flow of blood.

[@jloudefonty3231]

Very good tutorial, please continue

[@DhirajKumar-rd6vr]

very helpful video. please make a video on how to apply a non uniform (gaussian) heat flux on wall of tube

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

[@eamona708]

thank you, saved me hours

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??

[@FelixFrankie]

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!

Thank you Ahmad

[@prashantsaini6372]

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.

great one! thanks a lot

Heyy.I need suggestions and help to write for 3d pipe flow udf coding. TIA

[@zara9305]

Hi Sir, thanks so much, I'm wondering to ask the Nusselt number and temperature gradient UDFs

[@shivabairisn]

How can we add a profile equation at the outlet?

[@gabrielagambetta7819]

hi, if my problem is steady state i have to change "realt=CURRENT_TIME;" ??

Hello, can you share the note of UDF parameter? Thank you

Error: floating point exception Error Object: #f What does it mean ?

[@AhmadKouta]

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 😊
