LS-DYNA

Legacy documentation This page describes a service provided by a retired ACENET system. Most ACENET services are currently provided by national systems, for which please visit https://docs.computecanada.ca.

Short Description

LS-DYNA is a multifunctional applicable explicit and implicit Finite-Element program to simulate and analyse highly nonlinear physical phenomenons obtained in real world problems. Usually those phenomenons are subjected to large deformations within a short time duration, e.g. crashworthiness simulations.

Licensing

LICENSE HAS EXPIRED

Ordinarily, the license only covers the Dalhousie University Department of Mechanical Engineering. Members of that department should contact support and ask to be added to the Access Control List for LS-DYNA. Other users who wish access to LS-DYNA can contact support to discuss the cost of extending the license to their group.

Availability

Usage

Here is an example of a submission script:

#$ -cwd
#$ -pe ompi* 2
#$ -l h_rt=1:0:0,h_vmem=1G

module load lsdyna
mpirun lsdyna_mpp_s I=ring_1.k

See Job Control for a longer discussion of job scripts and parameters.

Memory

In our initial tests we found that if we did not request sufficient memory (h_vmem=), LS-DYNA would terminate with an uninformative error message or no message at all. If you get an unexplained crash, try increasing h_vmem.
