Ansys optiSLang Virtual Desktop

Ansys optiSLang is supported on Windows and Linux virtual desktops.

To establish a simulation workflow by connecting a solver to optiSLang, both the solver and optiSLang must be installed on a virtual desktop, and the solver must be functioning on the virtual desktop.

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

When creating a virtual desktop with Ansys optiSLang, 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 optiSLang

    The Windows package automatically adds Mozilla Firefox. The Linux package automatically adds XRDP for GNOME and GNOME Desktop Latest Version.

    If installing the 2024 R1 version of Ansys optiSLang, you must specify licensing settings in the application's configuration pane. For information on the available settings, refer to Configuring Applications in the Administration Guide.

    Note:

    • For a Windows virtual desktop, 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.

    • Ansys optiSLang packages include the optiSLang application and a Service Pack update. When using other Ansys applications with optiSLang, make sure that you use the same Service Pack version of those applications. For example, if using Ansys optiSLang 2025 R2, which contains the Service Pack 3 update, use the 2025 R2 Service Pack 3 version of Ansys applications. For details of available application versions, see Ansys Applications.

  • Hardware: m4, m5, c4, c5 (.*xlarge sizes) with at least 4 physical cores, 16 GB RAM, and 256 GB SSD

    Note:

    • A workflow that runs on a local configuration will run on a similar configuration on a virtual desktop.

    • Higher CPU frequency and in some cases more CPU cores will accelerate execution.

    • With more CPU cores, memory demand may increase.

    • Hyper-Threading (Intel CPUs) or Simultaneous Multithreading (AMD CPUs) can be enabled to optimize usage of computing resources.

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.
