Batch Processing and auto-save option
 
Hi,

I am trying to run an unsteady case with FLUENT using the batch processing option. I am having some trouble with the auto-save option when the run-script is used in the batch-mode (run-script attached below).

(1) Even though the auto-save frequency is set to 10, no case or data files are generated at the end of the simulation.

(2) I know there is a brute-force solution to this problem by writing a script

it 20 wc RT1_0020.cas wd RT1_0020.dat

it 20 wc RT1_0040.cas wd RT1_0040.dat

.... .... .... etc.

Is there a way of getting around this using loops?

Thanks

would you pls tell me what did you do? I have the same problem.

Re: Batch Processing and auto-save option
 
I have included the batch script that I used for an unsteady run. For a steady run, the batch-script given in the FLUENT user manual is sufficient. Hope this helps.
