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.

Formerly known as Fluent /Gambit, a computer program for modeling fluid flow and heat transfer in complex geometries. Gambit is a pre-processor for geometry modeling and mesh generation. TGrid is a preprocessor for generating volume meshes from boundary meshes.

Launching Fluent from DECS Compute Servers

If you intend to run Fluent on a compute server, you must be running an X environment to display the GUI.  Set up this environment by running X2Go on your local workstation.

Setting the environment

You can set the environment for a session by typing source $SOFT/ansys at the command prompt.

If you will be using Ansys on a regular basis, you can add the following lines to your .cshrc file:

if (-e $SOFT/ansys) then
source $SOFT/ansys

After editing your .cshrc, if you do not log out and log back in, it will be necessary to source your .cshrc. To do this, simply enter the command source .cshrc

Now each time you login, your environment will be set to run Fluent.

Launching Fluent

To launch Fluent, type fluent
