Minnesota Supercomputing Institute
With regards to the safety measures put in place by the university to mitigate the risks of the COVID-19 virus, at this time all MSI systems will remain operational and can be accessed remotely as usual. The only planned outages concern our in-person Helpdesk and tutorials. More information, as well as alternative remote support options, can be found at MSI COVID-19 Continuity Plan

FLUENT uses a finite volume numerical procedure to solve the differential equations governing fluid flow, as well as conservation of energy and chemical species therein. Both compressible and incompressible flows can be modeled, as can turbulence by way of the k-e turbulence model.
FLUENT is part of the ANSYS suite of software, and can be run either directly from the command line or under the ANSYS workbench. To run FLUENT in the ANSYS workbench see documentation for ANSYS. MSI has leased ANSYS Academic Research licenses. The default licenses are commercial. Before running FLUENT you will need to set licence preferences through the ANSYS workbench. Start the workbench with
module load ansys
Then open the "License Preferences" menu (under the Tools pull-down) and select "Use Academic Licenses" in the "Global Settings" section under the Solver tab. Then click OK and close the workbench.
Example: PBS Batch script for using ANSYS 18.1 across 2 nodes (48 cores):
#PBS -l walltime=00:10:00,nodes=2:ppn=24
module load ansys/18.1
fluent 3ddp -t 48 -mpi=intel -ssh -pinfiniband -cnf=$PBS_NODEFILE -g < run.in > run.out
