This topic lists issues that you may encounter with starting Workbench or Workbench graphics.

To minimize graphics problems, always verify that you are running the latest graphics drivers provided by your computer's hardware manufacturer. If you are not, you may see the following message:

***An error occurred while setting up the graphics window. Please ensure that you have the latest drivers 
from your graphics card manufacturer. If the error persists, you may need to decrease the graphics 
acceleration. For more information, please see the Troubleshooting section in the Ansys Workbench help.

Linux

If you are running Workbench on Linux and experience problems at startup or with the user interface or graphics displaying correctly, and you are running in accelerated graphics mode, you may need to relaunch Workbench using the -oglmesa flag to activate software rendering:

runwb2 -oglmesa

If Workbench detects that graphics problems are causing crashes, it automatically switches to software rendering. Workbench also uses software rending mode by default when running on a remote display, or on a local display if the hardware does not appear to be accelerated.

To revert to accelerated graphics mode, launch Workbench using the -oglhw flag:

runwb2 -oglhw

If you are running under Exceed3D, try the following settings if you are having graphics problems:

Any version of Exceed that does not have the GLX 1.3 option is unlikely to function correctly with graphics acceleration.

Windows

If you experience graphics issues on Windows systems, you can find the details of your graphics card and the driver that is currently installed by selecting Start > Run and typing the following into the Open field:

dxdiag

Select the Display tab and review your graphics card information. You can then contact the vendor or visit the vendor's website for details of the latest graphics drivers available for your specific graphics card.

You may also have to adjust the hardware acceleration. To adjust the hardware acceleration, Open Control Panel and select Display > Settings > Advanced > Troubleshoot or your operating system's equivalent. The hardware acceleration slider should then be visible. You can also select Display > Settings > Troubleshoot and use the troubleshooting tool to guide you to the Hardware Acceleration panel. Try turning hardware acceleration off by dragging the slider to None. Try the software again; if the graphics problems are resolved, then gradually increase Hardware Acceleration as far as you can before the software fails again.
