FLUENT

FLUENT is a computational fluid dynamics solver that provides a wide array of advanced physical models for turbulence, combustion, and multiphase applications. 

Access to FLUENT is restricted. 

FLUENT is an ANSYS product, and you must have access to ANSYS to use FLUENT.

Corporate users must negotiate licensing with ANSYS, Inc. and arrange for an allocation with PSC. Contact the PSC Corporate Relations office to discuss an allocation of time.

Academic users must have a valid PSC account and be at an institution which has a local ANSYS license.

• If you don't have a valid PSC account, see the instructions about applying.
• If you don't know whether or not your institution has a local ANSYS license, contact your departmental or campus computing services to find out.

When you meet these requirements, please complete this form to request access to ANSYS.

Installed on blacklight and warhol.

Blacklight Usage

1. Prepare a batch job containing commands to
   1. Set up the module command
   2. Load the correct ansys module for the version you wish to run.

      See documentation on the module software to determine

      • which versions are available
      • how to load the version you want

      To load the default version, type

      module load ansys

   3. Run fluent, using a command similar to:

      fluent [version] -g -p -tx -i sample.input

      where version can be "2d", "2ddp", etc., ( see General usage below) and x is the number of processors that you want to use.
2. Submit the job with the qsub command.

Warhol Usage

To run a fluent job on warhol:

1. Prepare a batch job containing commands to
   1. Set up the module command
   2. Load the correct ansys module for the version you wish to run.

      See documentation on the module software to determine

      • which versions are available
      • how to load the version you want

      To load the default version, type

      module load ansys

   3. Run fluent, using a command similar to:

      fluent version -g -p -t x -i input > output

      where version can be "2d", "2ddp", etc., ( see General usage below) and x is the number of cores that you want to use.
2. Submit the job with the qsub command.

Fluent general usage

To start fluent, type:

fluent [version] [-help] [options]

fluent -v lists the available versions, e.g.:

fluent - help lists all the options. One important option is -g, which disables the graphical user interface.

Use the text user interface. It has a hierarchical menu of commands. Once you have started Fluent, hitting <return> displays a list of the commands available at that level. Top level commands are: adapt, display, define, file, grid, plot, report, solve, surface, view, and exit.

Entering one of these commands takes you into that command's submenu. The prompt changes to indicate where you are in the menu hierarchy. Again, typing <return> lists all available (sub)commands at that level. For example, entering the view command, and then hitting <return> produces this list: (user input in italics)

> view
/view> <return>
auto-scale         delete-view       read-views
camera/            list-views        save-view
default-view       restore-view      write-views

The "/" after "camera" in the above list indicates that "camera" is not a command but another submenu. The remaining choices from the view menu are commands. Typing "camera" at the "/view>" prompt produces this:

/view> camera
/view/camera> <return>
dolly-camera        position          up-vector
field               projection        zoom-camera
orbit-camera        roll-camera
pan-camera          target
