How to save images of contour plots during parallel job

I use Fluent 6.3 and I would like to create and save images of contour plots automatically, when my job is running in parallel on a cluster. The images will then be used to create an animation of the unsteady flow.

The problem is that the job is running without graphic interface. So I cannot use basic commands as display, hardcopy, etc.

I know that another solution consists of saving a data file (.dat) each time I want to save an image and then, post processing the data (for space disk reasons). But this solution does not suit me because it takes too much hard disk space and time.

Have you any suggestions?

Thx in advance

I have the same problem with you...
I am using Fluent 12.1..

Let's wait for others' suggestions..

Hi Lawrence,

I found the solution (for Fluent 6.3)

Before, i used this command to run my job:
"Fluent 3d -g ... journal.jou
The "-g" disables all graphic tools.

Now, I use this command to run my job and it works...
"Fluent 3d -gu -driver x11 ... journal.jou"
With "-gu", the GUI is disables but not the graphics...
So, you can use, in your journal file, the commands "display", "hardcopy",... to save images. Or you can also create a macro if you don't want to modify your journal file.

bye bye
