LS-DYNA

LS-DYNA is a general-purpose finite element program for highly nonlinear, transient dynamic analysis using explicit time integration.

 

Category:  Engineering

Usage Notes
To show the software versions:
    module avail lsdyna

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

Additional Information
LS-DYNA is a licensed product and may not be available to all CCR users. Access is restricted. Contact ccr-help with inquiries regarding access to the LS-DYNA software.

The LS-DYNA graphical interface (lsprepost) benefits from using the CCR's remote visualization node.

Many LS-DYNA examples are available for download from the vendor's website.

LS-DYNA manuals are also available from the vendor's website.

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/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/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/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/slurm-scripts/slurm-mppdyna

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