1. Prepare your Fluent job using Fluent from the Ansys Workbench on your desktop machine up to the point where you would run the calculation.
2. Export the "case" file with File > Export > Case… or find the folder where Fluent saves your project's files. The case file will often have a name like FFF-1.cas.gz.
3. If you already have data from a previous calculation, which you want to continue, export a "data" file as well (File > Export > Data…) or find it in the same project folder (FFF-1.dat.gz).
4. Transfer the case file (and if needed the data file) to a directory on the /project or /scratch filesystem on the cluster. When exporting, you can save the file(s) under a more instructive name than FFF-1.* or rename them when they are uploaded.
5. Now you need to create a "journal" file. It's purpose is to load the case file (and optionally the data file), run the solver and finally write the results. See examples below and remember to adjust the filenames and desired number of iterations.
6. If jobs frequently fail to start due to license shortages and manual resubmission of failed jobs is not convenient, consider modifying your script to requeue your job (up to 4 times) as shown under the by node + requeue tab further below. Be aware that doing this will also requeue simulations that fail due to non-license related issues (such as divergence), resulting in lost compute time. Therefore it is strongly recommended to monitor and inspect each Slurm output file to confirm each requeue attempt is license related. When it is determined that a job is requeued due to a simulation issue, immediately manually kill the job progression with scancel jobid and correct the problem.
7. After running the job, you can download the data file and import it back into Fluent with File > Import > Data….
