my UDF is based on flow time in transient flow analysis, after 300 time step it generates new velocity value and inlet, outlet pressure value.

also on 300th time step, data is autosaved in .dat and .cas files.

is it possible to write UDF or TUI commands set, to create .xy plot files using fluent inbuilt post processing plots option. at 300th time step.

Yes, with a journal file for example. Look for that in the Fluent manual.

Hi,


I always avoid UDFs whenever possible. You can do that with a journal file. You can call a journal every X iterations or timesteps by creating a command in the calculation activities tab. Something like:


/file/read-journal magic_journal.jou ()


In the magic_journal.jou file you will include the commands to save the pictures you want (of course instead of calling the journal you can just write them all in the execute commands box). It is important to include the iteration or the timestep in the naming of the pictures, otherwise it will always overwrite it.


You can do that by including the string %i for iterations or %t for the timestep in the file name you are giving to the picture. More information here.
