LS-OPT

Environment

The ls-opt module is provided for setting up your environment for LS-OPT.

Documentation

The PDF documentation can be found at $LSOPT_HOME/lsopt_XX_manual.pdf (eg. lsopt_42_manual.pdf for version 4.2 on Eos) on the system where it is installed. $LSOPT_HOME is available after you load the ls-opt module.

Batch Jobs

LS-OPT can submit jobs to the batch system for running LS-DYNA simulations. This section provides driver scripts that can submit serial, MPI, and OpenMP jobs to run LS-DYNA for TORQUE on Eos. These driver scripts are based on the examples from Section 9.12 of the LS-OPT 4.1 User's Manual.

First, specify the following in your command file for LS-OPT to use the driver script to submit jobs to the batch system on Eos:

solver command "/full/path/to/script/driver_script_name"
solver concurrent jobs 0
solver queue pbs

Then, use one of the below driver scripts that can be used with LS-OPT to spawn LS-DYNA jobs. The driver script MUST have executable permissions. So run the following command to add executable permissions for the driver script:

chmod +x driver_script_name

For more information about LS-DYNA, see the LS-DYNA FAQ page.
