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 R12.1 executables: C:\LSDYNA-R14.1.0

    • LS-RUN: C:\Program Files\LSTC\LS-Run.exe

    • LS-PrePost (if app selected): C:\Program Files\LSTC\LS-PrePost-4.10.6

    • Intel MPI: C:\MPI_commonfiles\MPI\Intel\2018.3.210\winx64\bin\mpirun.bat

    • Microsoft MPI: C:\MPI_commonfiles\MPI\Microsoft\10.1.12498.18\winx64\Bin\mpiexec.exe

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

    • LS-RUN: C:\Program Files\LSTC\LS-Run.exe

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

    • Intel MPI: C:\MPI_commonfiles\MPI\Intel\2018.3.210\winx64\bin\mpirun.bat

    • Microsoft MPI: C:\MPI_commonfiles\MPI\Microsoft\10.1.12498.18\winx64\bin\mpiexec.exe

    Note:

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

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

    • There are symbolic links to LS-RUN, LS-DYNA, and LS-PrePost in the C-disk root directory.

  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.
