====== ANSYS Workbench ======

> Ansys Workbench combines access to ANSYS applications with utilities that manage the product workflow.
> Workbench allows you to construct projects composed of multiple dependent systems that can be updated sequentially based on a workflow defined by the project schematic.

Workbench is included with ANSYS as part of our Newcastle University licensing agreement to all users of the HPC facilities.

===== Running on Comet =====

To use ANSYS Workbench on Comet, please read the main [[:advanced:software:ansys|ANSYS guide]] first.

----

===== Starting Workbench =====

The ANSYS Workbench (//and all graphical tools launched from within it//) can now be run on Comet. To do so start a new [[advanced:software:x11|X11 desktop session]] using our [[advanced:interactive|Open OnDemand]] service. 

<WRAP important round box>
**Comet GPU nodes and ANSYS**

Using a GPU node for ANSYS Workbench //display// is unsupported. GPU nodes are __only__ to be used for accelerated //ANSYS Mechanical APDL solvers// or batch-mode //Fluent compute jobs//.

Unless you are using Workbench to run Mechanical APDL //solvers// you should therefore **not** assign a GPU card, and should only ever use the __VNC Desktop__ session option from our [[advanced:interactive|Open OnDemand]] service. Please **do not** use the __VNC Desktop (GPU)__ session option - this is //unsupported//.
</WRAP>

   * Start the VNC Desktop session

   * Open the terminal application from the bottom bar:

{{:advanced:software:ansys_desktop_terminal.png?800|}}

   * In the terminal window, type the commands to load the ANSYS container and start ANSYS Workbench

<code lang=bash>
$ source /nobackup/shared/containers/ansys.2025r2.sh
$ container.run runwb2
</code>

{{:advanced:software:ansys_desktop_terminal_commands.png?800|}}

   * The ANSYS splash logo should show...

{{:advanced:software:ansys_workbench_splash.png?800|}}

   * Then the ANSYS Workbench application will start:

{{:advanced:software:ansys_desktop_workbench_ui.png?800|}}

You should now be able to run any of the installed ANSYS tools directly from the Workbench application. 

<WRAP info round box>
Remember to log off and close the VNC Desktop session down when you are finished - your HPC project account will continue to accrue time against the allocated resources whilst the VNC Desktop session runs, even if you are not actively using it.
