Required: Basic knowledge about metamodel-based optimization and result analysis using LS-OPT.
Strongly recommended: Introduction to LS-OPT class since it provides a foundation for some of the advanced topics.
Recommended but not required: An introductory class in LS-DYNA® for familiarity with a few keywords.
Syllabus
This course is intended to help engineers with a basic knowledge of LS-DYNA and LS-OPT to become proficient in advanced optimization and probabilistic design methods. With this course we hope for you to become more productive at design and parameter identification of complex systems, such as multidisciplinary systems with competing objectives, advanced material testing and models, and systems with discontinuous responses. We will also provide insight into reliability and robustness in order to facilitate higher quality product design. Additionally, we will introduce classification-based adaptive sampling constraints as a tool for enhancing the efficiency.
In this course, we will discuss both the theoretical and practical aspects of design. We will also cover advanced topics, such as multi-objective and collaborative optimization, digital image correlation, statistical classification, and probabilistic optimization. During workshop sessions, we will apply the discussed theoretical topics. We will use the LS-OPT Version 6.0 graphical user interface to teach input preparation and post-processing. We will also emphasize interfacing with LS-DYNA.
