If you intend to run Fluent 13.0 on a compute server you must be running an X environment to display the GUI. On a Windows machine setup this environment by running Xming on your local workstation.
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
endif
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.
To launch Fluent 13.0 type:
