6.10. LS-DYNA

LS-Run

  • If you try to run a remote job in LS-Run with IntelMPI 2018.3.210 specified, which is the included version for 2025 R1, LS-DYNA doesn't start and you get an error message.

    To correct this you need to install the 2021.8.0 version of IntelMPI, which is included in the product installer but not installed automatically if you only install LS-DYNA.

    In the product installer files, locate the folder \v251\winx64\tp\mpi. Open the WINX64.7z archive and extract it to the Ansys Inc\v251\ folder.

    This will install several IntelMPI versions.

    In LS-Run, you can now specify IntelMPI 2021.8.0. For example, you would enter into the Expression field: call “C:\Program Files\ANSYS Inc\v251\tp\MPI\Intel\2021.8.0\winx64\env\vars.bat” && mpiexec -localonly -np $NCPU “$Solver” i=$INPUT memory=$MEMORY
