LS-DYNA is a general-purpose finite element program for highly nonlinear, transient dynamic analysis using explicit time integration.
Availability: LS-DYNA is a licensed product and is not available to all CCR users. Access is restricted. Contact ccr-help with inquiries regarding access to the software.
To show the software versions: module avail lsdyna
Loading the module will set the path and any necessary variables: module load lsdyna/version
- The LS-DYNA graphical interface (lsprepost) benefits from using the CCR's remote visualization nodes in the OnDemand Portal, but can sometimes fail to load on the viz nodes. See the remote visualization using the OnDemand portal KB article for more information
- Many LS-DYNA examples are available for download from the vendor's website.
- LS-DYNA manuals are also available from the vendor's website.
- On March 6, 2015, COMSOL and UB CCR hosted a computer modeling workshop focusing on COMSOL and other commercial engineering solvers. The workshop included instructions for using the UB CCR cluster to accelerate a variety of engineering codes, including COMSOL, ABAQUS, LSDYNA, ANSYS/CFX, STARCD, and STARCCM+.

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