Software Description
Software Description: 

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.

        #!/bin/bash -l
        #PBS -l walltime=00:10:00,nodes=2:ppn=24
        module load ansys/18.1
        cd $PBS_O_WORKDIR
