Definition
LS-DYNA is an advanced general-purpose multiphysics simulation software package
Ansys LS-DYNA on Euler
On Euler the following versions of Ansys LS-DYNA are available through modules:
| Version | Module command |
|---|---|
| Ansys Research 2024 R2 | module load ansys/24.2_research |
| Ansys Teaching 2024 R2 | module load ansys/24.2_teaching |
| Ansys Research 2023 R1 | module load ansys/23.1_research |
| Ansys Teaching 2023 R1 | module load ansys/23.1_teaching |
| Ansys Electronics Research 2024 R2 | module load ansys_em/24.2_research |
| Ansys Electronics Teaching 2024 R2 | module load ansys_em/24.2_teaching |
Licenses are available in the ETH IT Shop.
Teaching licenses can only be loaded by ETH students.
Manuals: 23.1
Multi-node execution
Because Ansys LS-DYNA does not support Slurm, a list of available nodes has to be provided to it.
Example jobscript:
#!/bin/bash
#SBATCH --nodes=1
#SBATCH --ntasks=8
#SBATCH --time=8:00:00
#SBATCH --constraint=ib # request InfiniBand network for MPI job
# Load ANSYS module
module load ansys/23.1_research
# Required for running ANSYS products with Slurm
unset SLURM_GTIDS
# Extract hostname and number of tasks per node from SLURM
machines=""
for i in $(scontrol show hostnames=$SLURM_JOB_NODELIST); do
machines=$machines:$i:$SLURM_NTASKS_PER_NODE
done
machines=${machines:1}
echo $machines # For logging
# Set variables for old IntelMPI
unset I_MPI_PMI_LIBRARY
export FI_PROVIDER=verbs
# Set ANSYS input file and solver
lsdyna231 -dp -mpp i=./input.k -machines $machines
