Ansys Rocky Virtual Desktop

Ansys Rocky is supported on Windows virtual desktops.

Follow the instructions in Creating a Virtual Desktop in the Administration Guide.

When creating the virtual desktop, use the following guidelines:

  • Operating system: Windows or Linux

    On Windows, Ansys 2025 R2 applications are only supported on the Windows Server 2022 operating system, while 2025 R1 and earlier releases are supported on both Windows Server 2022 and Windows Server 2019.

    If creating a Linux virtual desktop using the Rocky Linux by CIQ image, see What You Should Know About the Rocky Linux OS Image by CIQ in the Administration Guide.

    If creating a Linux virtual desktop using the CentOS image, see Important Notes About CentOS Linux Images in the Administration Guide.

  • Applications: Ansys Rocky

    If you are creating a Linux virtual desktop, you may also want to add either KDE Desktop Environment or GNOME Desktop Latest Version to the list of applications to be installed.

    For the Ansys Rocky application, specify the Interconnect Port number (if different than the default port number).

    If you are installing the 2024 R1 version of Ansys Rocky, you must also specify the hostname or IP address of the License Server as well as the Flexnet Port number (if different than the default port number).

    Note: Ansys recommends that you create the virtual desktop without any applications, and then add the application after the virtual desktop has been created. See Adding Applications to a Virtual Desktop in the User's Guide. Sometimes, Windows updates are triggered on newly created virtual machines, causing application installation to fail.

  • Hardware: A g5 or g4dn instance type is recommended. CPU, single-GPU, and multi-GPU compute is supported.

    In the GPU driver options, GRID drivers are recommended for accelerated graphics. For GPU compute, both GRID and Tesla drivers are supported.

    For information about GPU driver options, see NVIDIA GPU Driver Support.

    Note: For Rocky 2024 R2 or later, the Tesla M60 graphics card is not recommended.

When the resource is in the Running state and the Connect button is displayed, you can connect to the virtual desktop. See Launching a Virtual Desktop Session in the User's Guide.
