hi pal,

Can you help me out in this by sending if u could have the simlar one by sending to me?

hi pal,

In that UDF whih is in UDF source ,we got temperature varying for position and time as well. But I want only for time dependant temperature profile. pls do guide me

Hi inside the UDF user guide look for Define_profile example 7. copy and paste the example of target mass flow rate profile. instead mass flow label, you can change those names with temperature labels. delete the "if" statement if you don't need this feature. Inside the f_loop write your expression of temperature that will be function of time. for hooking this UDF I send back you to UDF user guide Hooking chapter. nothing of difficult how you can see. Forum help to guide towards the right way.

regards Dothan

Check the user manual for unsteady profiles. You can directly read data in the form of tables. Check page 7-11 of user guide for fluent6.3.26
