information from saved data files:Unsteady flow

July 18, 2008, 11:09

Hello,

I have saved data flies from a unsteady simulation. There are about 20000 data files from this particular simulation. Now I want to extract information like--temperature contours, velocity vectors, fluctuation at a particular point in my domain and others.

To get this information if I have to open all of the data files and get the plots, it will take me forever. Is there any way to automatically extract the information that I need from these saved data files? If there is any script or macro that I can use to do this?

Can anyone help me out with this?

Thanks and Regards, Atul

Thanks for the response umesh. Can u elaborate more on this? Do u mean that I can create a journal file for this to automatically read all of the data files and get data ?

this is one sample of my journal file which I used long time ago for unsteady simulation..... you may need to prepare like this.... the command for journal file you can find by simply press"ENTER" in fluent tui... more details you could find at following link

Dear Umesh, Thanks a lot for information. I will look into it and figure out how to use it for my case. Thanks again for help. Atul

Thanks for the information umesh. Are you writing these commands repetitively for all of the data files in your journal file?
