How to access the software

Check for available versions of the LS-DYNA module using:

module spider LS-DYNA

Load an available LS-DYNA module using:

module load LS-DYNA/<version>

Example Job Scripts

The following job scripts demonstrate how to run LS-DYNA within a Slurm job. Please note, that the scripts differ depending on whether you are using LSTC LS-DYNA modules or newer ANSYS LS-DYNA modules. These variants can be distinguished by their naming conventions: the former use the format LS-DYNA/R<version-number> (e.g. LS-DYNA/R13.1), while the latter use LS-DYNA/<year>R<version-number> (e.g. LS-DYNA/2025R1).

• Examples for LSTC LS-DYNA
• Examples for ANSYS LS-DYNA

LS-DYNA provides executables supporting single precision (sp), double precision (dp), shared-memory (SMP) and distributed-memory (MPP) parallel processing. Selecting the appropriate binary for your specific use case can significantly improve performance. An overview of the available solvers for both LSTC and ANSYS LS-DYNA versions is provided below.

LSTC LS-DYNA jobscripts (e.g. LS-DYNA/R13.1)

Serial Job

#!/usr/bin/zsh

### Job name
#SBATCH --job-name=LSDYNA_SERIAL

### File / path which STDOUT will be written to, the %J is the job id
#SBATCH --output=LSDYNA_SERIAL.%J

### Request the time you need for execution. The full format is D-HH:MM:SS
### You must at least specify minutes or days and hours and may add or
### leave out any other parameters
#SBATCH --time=80

### Load required modules
module load LS-DYNA/R13.1

### start non-interactive batch job
ls-dyna_smp_s i=inputfile

Currently there are no executables for module R13.1 for "Shared Memory" and "Distributed Memory Parallel Jobs".
