LS-OPT 3.1
Design Optimisation and Robust Design

LS-OPT by Livermore Software Technology Corp. (LSTC) is a versatile tool for design optimisation, robust design, and probabilistic analysis of physical systems. LS-OPT is very well suited to use together with the simulation software LS-DYNA.

Free of charge for LS-DYNA license holders

LS-OPT is available without extra charge for all current LS-DYNA license holders. The LS-OPT license key is already included in your existing LSTC license file and thus you are ready to start using LS-OPT as soon as you have downloaded and installed the software.

Applications

Examples of applications of LS-OPT are:

Automotive crashworthiness design
System identification:

Airbag gas generator parameters identification
Identification of material parameters from complex tests, e.g. ball rebound test of foam

Robustness analysis of passenger restraint systems
Metal forming optimisation

Product description

LS-OPT is very well integrated with LS-DYNA. LS-OPT has a user-friendly graphical pre- and postprocessor that also allows monitoring of the progress of the computations. LS-OPT offers a large set of tools and techniques of which some of the most important are:

Design optimisation:

SRSM Successive Response Surface Method
SSSM Successive Stocastic Search method
Gradient Based Optimization

Continuous and/or discrete design variables
Multi-Disciplinary Design optimisation
Neural Network meta models
Monte Carlo simulation
Stochastic contribution analysis
Sensitivity analysis
Stochastic fields for disturbing the finite element model geometry (requires LS-DYNA 971)

Consulting services

ERAB has consultants with a considerable expertise in using LS-OPT both for optimisation and statistical analysis. We have experience from using LS-OPT within the automotive and metal forming sectors. We can perform complete projects using LS-OPT or aid in the set up and use of LS-OPT for your particular application.

Training

We offer LS-OPT training courses on a regular basis; please see our course schedule for more information. We also offer customised courses that are given on-site.
