ALE, Eulerian, & Fluid-Structure Interaction in LS-DYNA®
Syllabus
This class provides new and experienced LS-DYNA users a deep understanding of the ALE and FSI capabilities in LS-DYNA. It delivers the skillset needed to solve ALE and FSI problems, including when and how to use ALE keywords. Several LS-DYNA input files, using different ALE and FSI applications (air blast, sloshing, hydrodynamic impact, underwater explosion,...) and covering different ALE and coupling keywords, will be provided and used during the workshop.
