Loading the module will set the path and any necessary variables:   module load lsdyna/version



Additional Information




Single Node (Shared Memory) Parallelism


LS-DYNA jobs can be launched in unattended "batch" mode using single node shared memory parallelism. An example SLURM script is available on the CCR front-end at:
/util/academic/slurm-scripts/slurm-lsdyna


An example LS-DYNA model configured to use shared memory and involving a ball and plate is available on the CCR front-end at:
/util/academic/lsdyna/example



Checkpoint and Restart of LS-DYNA Jobs


LS-DYNA jobs can be restarted in the event that a computation runs longer than the requested CCR job time. An example LS-DYNA model and corresponding checkpoint/restart SLURM scripts are available on the CCR front-end at:
/util/academic/lsdyna/example_restart



Multiple Node (Distributed Memory) Parallelism


Using MPPDYNA, LS-DYNA jobs can also be launched in unattended "batch" mode using multiple node distributed memory parallelism. An example SLURM script is available on the CCR front-end at:    /util/academic/slurm-scripts/slurm-mppdyna


The ball and plate example configured to use MPPDYNA is available on the CCR front-end at:    /util/academic/lsdyna/mpp_example

An MPPDYNA example that makes use of a pfile to configure the parallel job (see APPENDIX O of LS-DYNA Keyword Manual) is also available on the CCR front-end at:
/util/academic/lsdyna/mpp_pfile_example
