$ module load ansys/2021r1

There are also license licence 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 licence modulefile, for example, only members of ansys_nci group can see the license licence module `ansys_licence/nci`. The software group membership gives not only the access to the license licence module,  and also allows checkouts from the corresponding licensing server.

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  <licenselicence  <licence_string> , see details in the section `License `Licence requirements` below. To change the number of processors, memory, or jobfs required, and/or project folders to mount, simply modify the appropriate PBS resource requests at the top of this file.

The maximum number of CPU cores a CFX job can use is limited by the license licence availability. For example, NCI owns an academic ANSYS license licence file which has 128 seats for the hpc feature and it supports jobs request up to 128 CPU cores. If you submit many 128-core fluent jobs, they are expected to run one at a time.

...

If you need to run CFX 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.

Licence requirements

Users from the following institutions have access to their own institution licenses licences and should join the corresponding software group. To join a software group, 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 and ready for use. Run `module avail ansys` to list all ansys related modulefiles. Jobs need to load the license licence module together with the application module to run CFX.

* NCI owns an academic ANSYS license licence file which provides 25 CFD feature seats and 128 HPC feature seats. Users who have no access to the above licenses licences are welcome to join the software group ansys_nci to enable the access to modulefile ansys_licence/nci and the checkouts from licence ansys_nci.
