module load ansys/2021r1

There are also license module files modulefiles for users to configure where to check out ANSYS licence(s). Users need to join the corresponding ansys software group before they can see the license module file. The software group membership gives access to the license module, for , for example, only members of ansys_nci group can see the license module `ansys_licence/nci`, and . The software group membership not only gives the access to the license module but also allows checkouts from the corresponding licensing server.

A example job submission script (ansysjobfluentjob.sh) is provided below. It requests 96 processors, 380 GB of memory, 400GB of local disk space for 10 minutes in the normal queue and tells the job to mount /g/data/ab01 and /scratch/ab01 project folder into the job. Within the job it tells fluent to use the openmpi provided by Gadi instead of their own to run the simulation on $PBS_NCPUS processors.

#!/bin/csh
#PBS -q normal
#PBS -l walltime=00:10:00
#PBS -l ncpus=96
#PBS -l mem=380Gb
#PBS -l jobfs=400GB
#PBS -l storage=gdata/ab01+scratch/ab01
#PBS -l software=<license_string>
#PBS -l wd

module load ansys/2021r1
module load ansys_licence/<institution>
fluent 3ddp -g -mpi=hpcx -t $PBS_NCPUS -i test.jou >& outputfile

Note that the submission script uses the PBS directive`-l software`, to ask the job scheduler for the reservation of ansys licence seats from license <license_string> , see details in the section License requirements below. To change the number of processors, memory, or jobfs required, and/or project folders to mount, simply modify the appropriate corresponding PBS resource requests at the top of this file.

...

Once the job submission script is saved to the same directory in which the journal file test.jou is located, run 

qsub ansysjobfluentjob.sh 

inside that directory to submit your job to the PBS scheduler.

...

If you need to run Fluent for a very long period of time which exceeds the default walltime limit set for the job, see the walltime limit for different queues and number of cores on the Queue Limits page, we suggest to add checkpoints to the long job, save restart files and use the last one as input to the next job. 

License requirements

Users from the following institutions have access to their own institution licenses and should join the corresponding software group. To join the corresponding a software group in the table below, login to my.nci.org.au first, search for the group by the software group name, and use the tab `Join` on its project page to submit the membership request. It may take up to 1 business day for the lead CI to respond. Once your group membership request is approved, the corresponding licence module becomes visible to and ready for use. Run `module avail ansys` to list all ansys related modulefiles. Jobs need to load the license module together with the application module to run fluent.
