hello everyone

How can i get streamlines and isotherms at each instance in fluent?

[Rob]

By plotting them? I don't understand what you're after.

i wanna see the isotherms at 100s and at 300s and so on.

OK, then you either need to use TUI commands combined with Execute Commands in Fluent set to trigger at the time step during the run, or do the post processing after the run is complete either manually with each data set or by using a journal to do it.

it's better to do it after the run is complete. but i couldn't got you ...how can i use a journal is it a command?

[Rob]

Journal file - a text file containing a load of commands. If you're doing an action a few times it's generally quicker to do it manually, so read case & data, do post processing, read next case & data etc. For many files writing a journal is often more efficient.
