-CHPC has academic licenses for AnsysCFD. ​ There are 25 "​solver"​ processes, available as aa_r_cfd and 2048 "​HPC"​ licenses, available as aa_r_hpc. ​ A license resource management system has been activated. If you request license resources (as in these example scripts), the scheduler will check for license availability before starting a job.  License unavailability will result in the job being held back until the necessary licenses have become available. ​ Although use of the license resource request is not mandatory, its use is strongly recommended. ​ If you do not use the license resource requests, the job will fail if no licenses are available. ​ A single aa_r_cfd license is required to start the solver, and includes up to 16 HPC licenses. ​ Therefore you should request ($nproc-16) aa_r_hpc licenses. ​ **Do not request more than you need, it will delay the start of your job.**+CHPC has academic licenses for AnsysCFD.  ​If you are a new Ansys user on Lengau, [[https://​users.chpc.ac.za/​helpdesk/​tickets/​submit/​|submit a helpdesk ticket]], requesting access to the license.
