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

  • Applications: Ansys optiSLang

    The Linux package automatically adds XRDP for GNOME and Gnome Desktop Latest Version.

  • Hardware: Ansys recommends a VM size with at least 8 physical cores and 32 GB RAM. However, the size you choose depends on the solver to be connected to optiSLang, the size of the model, and the number of parallel computations expected. To determine the recommended virtual machine sizes for the solver, refer to Recommended Hardware for VDI Workflows.

    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.

    • Some VM sizes have Hyper-Threading (Intel CPUs) or Simultaneous Multithreading (AMD CPUs) enabled which can optimize usage of computing resources.

      To determine whether a VM size supports Hyper-Threading/multithreading, check the vCPUs column in the hardware table. Specifically, look for an information icon next to the number of vCPUs.

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.
