Hello,

I have problems setting up an ansys fluent jounal file that must be submitted to an HPC cluster. I am using the following commands:

rcd Cavity.cas

solve iterate 10000

wcd Cavity.cas

yes

quit

quit

quit

quit

quit

exit

yes

I submit it to the cluster through this command: sbatch --time=8:00:00 --mem-per-cpu=2g --tmp=2g --wrap="fluent 3d -i Cavity_journal.jou

The job is submitted correctly because the status of the job is "Running" but I don't get any output case (.cas) nor data (.dat) file. Is it a problem of the journal file and what should I change? 

Thanks for the answer:)

It's generally safer to run:

/file/rcd Cavity.cas

/solve/iterate 1000

/file/wcd Cavity_%i

etc

 

If you take shortcuts in the commands if Fluent isn't in the correct menu level the command will fail. If that's happened you may see an error in the transcript file. I'd also advise against overwriting files like that in case anything goes wrong. If it does you've lost both the results and potentially the input files.  Look up %i, %t and %f in the User's Guide: they're useful.

Oh, and check the commands one by one locally before firing off a batch run. Especially anything I write in as I may have missed something.
