10.4. System-Dependent Graphics Information

This section describes factors affecting how ANSYS graphics display on different hardware systems.You
should read this information before you activate the ANSYS graphical user interface.

10.4.1. Adjusting Input Focus

To enable the display, meshing, and listing interrupts to work correctly, you must set the input focus
in the text window from which the ANSYS program is executing. You can set the focus in either of two
ways:

• Position the mouse pointer within the text window. (Use this method only if the window manager
  sets the focus automatically.)


• Place the mouse pointer on the text window and click the mouse button.

10.4.2. Deactivating Backing Store

When you are using the X11 graphics driver on Sun SPARC systems, backing store is turned on by default.
For faster graphics response turn backing store off by issuing the command shown below:

setenv ANSBACK 0

10.4.3. Setting Up IBM RS/6000 3-D OpenGL Supported Graphics Adapters

For 3-D OpenGL, initialize the window manager using the command below:

xinit -- -x abx -x dbx -x glx

3-D OpenGL does not apply to Sabine, GT4E, and GT0 graphics adapters.

10.4.4. Displaying X11 Graphics over Networks

You can display X11 graphics within the ANSYS program over the network if the following conditions
exist:

• All computer systems have X11 software installed.


• The ANSYS program is linked with the X11 driver.


• A /SHOW device type of x11 or x11c is used. (You can use either uppercase or lowercase characters
  to specify device types.)


• The /etc/hosts file on the host machine contains the hostname and the IP address of the remote
  machine.


• The environment variable DISPLAY is set to Hostname:0.0, where Hostname is either the host name
  or the IP address of the machine that will display the graphics.

For example, suppose that you want to run the ANSYS program remotely from another UNIX system
for local display of X11 graphics on your workstation monitor. You would perform these steps:

1. Open a window on your workstation and issue the following command to authorize remote hosts
   to access the display:
   /usr/bin/X11/xhost +
