ANSYS FLUENT software contains the broad physical modeling capabilities needed to model flow, turbulence, heat transfer, and reactions for industrial applications ranging from air flow over an aircraft wing to combustion in a furnace, from bubble columns to oil platforms, from blood flow to semiconductor manufacturing, and from clean room design to wastewater treatment plants. Special models that give the software the ability to model in-cylinder combustion, aeroacoustics, turbomachinery, and multiphase systems have served to broaden its reach.
To load the default ANSYS module:
module load ansys

Setting License Type
Before you can run FLUENT, each user must first set the license type to ANSYS Academic Research CFD or ANSYS Acedemic Teaching CFD.
From a CRC front-end node, run the following command (which will invoke, per user, the license admin GUI) :
For 14.5, /afs/crc.nd.edu/x86_64_linux/ansys/v14.5/shared_files/licensing/lic_admin/anslic_admin
For 15.0, /afs/crc.nd.edu/x86_64_linux/ansys/v15.0/ansys_inc/shared_files/licensing/lic_admin/anslic_admin
For 16.2, /afs/crc.nd.edu/x86_64_linux/a/ansys/16.2/shared_files/licensing/lic_admin/anslic_admin
To set the license type, perform the following for version 14.5:
# Click on "Set License Preferences for User netID" # Select the latest ANSYS v14.5 (if asked) or any version number you wanted. # Select one of the "ANSYS Academic Teaching CFD" or "ANSYS Academic Research CFD" license entries # Click "Move up" or "Move down" button on the right-hand-side to give your license preference. For example, if you want to use "ANSYS Academic Teaching CFD", click "Move up" if it is in the lower place. # Click "Apply" to store settings and "OK" # From "File" Menu (upper left), click "Exit"
To set the license type, perform the following for version 15.0 ans 16.2:
# Click on "Set License Preferences for User netID" # Select the latest ANSYS v15.0 or 16.2 (if asked) or any version number you wanted. # Select one of the "ANSYS Academic Teaching Advanced (or DesignSpace)" license entries # Click "Move up" or "Move down" button on the right-hand-side to give your license preference. For example, if you want to use "ANSYS Academic Teaching Advanced ", click "Move up" if it is in the lower place. # Click "Apply" to store settings and "OK" # From "File" Menu (upper left), click "Exit"
This process will create a local settings file in $HOME/.ansys/$ANSYS_Version/licensing/license.preferences.xml
Checking Available Number of License

FLUENT can be invoked interactively on the command line as follows:
The displays the FLUENT Launcher which you can use to customize your session.
For ANSYS 14.0, you may need to add a graphics driver option when using a machine which does not have a graphics card.
> fluent -driver x11 2ddp
A typical FLUENT submission script looks as follows:
#!/bin/csh #$ -M email@example.com #$ -m abe #$ -pe smp 1 #$ -q long #$ -v DISPLAY #$ -w e #$ -cwd module load ansys fluent 3ddp -t$NSLOTS # Run 3D Double Precision Version
FLUENT jobs can be run over multiple processes by using the -t# command line option:
fluent 3ddp -t16 ...
In this example, the parameter requests that 16 processes/tasks be used in the parallel calculation.
Note: Make sure to change your submission script's parallel environment to match the number of processors you plan to run on e.g.
#$ -pe mpi-8 16
