29.1.6 Hiding the Graphics Window Display

There may be situations where displaying graphics on a local machine is not practical, such as when running ANSYS FLUENT using the RSF (Section  1.1.6). Therefore, you may decide to hide (or disable) the graphics display window.

To disable the graphics display window when starting ANSYS FLUENT from the command line, you can specify the driver as null:

fluent -driver null

For a ANSYS FLUENT session that is already in progress, the graphics window display can be disabled using the following TUI command:

display $\rightarrow$ set $\rightarrow$ rendering-options $\rightarrow$ driver $\rightarrow$ null

All graphics windows must be closed prior to invoking the above TUI command.

If the graphics window display is disabled, you can continue to save graphics using the Save Picture option, as described in Section  4.21. The saved graphics files will be identical whether the graphics window display is enabled or disabled.

For a ANSYS FLUENT session that is already in progress, to re-enable a graphics window display that had been previously disabled, use the following TUI command:

display $\rightarrow$ set $\rightarrow$ rendering-options $\rightarrow$ driver $\rightarrow$ opengl

If any graphics windows are open (which are not visible to you), ANSYS FLUENT will prompt you to close all open windows. You can close them using the following Scheme command:

(close-all-open-windows)

and then retype the TUI command to enable the graphics windows.

If you happen to be logged on to a machine remotely, then opengl may not work on your system. Use x11 instead to enable your graphics windows.
