Run a Windows LS-DYNA Virtual Desktop

If a Windows virtual desktop with LS-DYNA has been added to a project space, follow the steps below to connect to the virtual desktop and launch a virtual desktop session. (For Linux, go to Run a Linux LS-DYNA Virtual Desktop.)

  1. Connect to the virtual desktop as described in Launching a Virtual Desktop Session in the User's Guide.

  2. Open a command prompt. Navigate to C-disk root directory. There you can see your LS-DYNA installations. For example:

    • LS-DYNA R14.1 executables: C:\LSDYNA\LSDYNA-R14.1.1-8

    • LS-RUN: C:\LS-RUN\LS-Run.exe

    • LS-PrePost (if app selected): C:\LS-PREPOST\lsprepost4.11.exe

    • Intel MPI: C:\LSDYNA\MPI\Intel

    • Microsoft MPI: C:\LSDYNA\MPI\Microsoft

    Note:

    • LS-Prepost can be accessed anywhere with batch lspp or lsprepost.

    • Intel MPI can be accessed anywhere with the mpirun command.

  3. All required environmental variables and licensing to run LS-DYNA are already set. Add input files using your mapped NFS drive and scp. Execute LS-DYNA on the command line or with LS-Run.

    mpirun -np <cores>  C:\LSDYNA-R14.1.0\mpp-dyna\ls-dyna_mpp_s_R14.1_205-geb5348f751_winx64_ifort190_impi2019.exe i=input.k
    Note: For Intel MPI, the mpirun should be used rather than the full path to MPI. mpirun is a batch file that calls Intel MPI with option -localonly, which is required on Ansys Gateway powered by AWS.

    For information about LS-DYNA, refer to the LS-DYNA Documentation.

    If you need to transfer files to the virtual desktop, see General Guidelines for Transferring Files in the User's Guide.
