Reading a well-annotated keyword deck is often faster than watching a video.
LSTC (Livermore Software Technology Corp), now part of Ansys, provides the official manuals for free in PDF format. These are not "click-next" video tutorials but are the definitive guide for setting up any simulation.
Unlike GUI-based software, LS-DYNA’s input deck is human-readable. Open any example .k file in a text editor (Notepad++ or VS Code with LS-DYNA syntax highlighting). The comments (lines starting with $) often explain why a parameter is set to 0.5 or 1e-4. That is your real teacher.
Get started today: Google "ls-dyna verification manual pdf" and download the first result. Then run the Taylor Impact test. You will learn more in 30 minutes than from hours of passive video watching.
Open Source Models
Many researchers publish their LS-DYNA input decks on GitHub. Search for ls-dyna keyword file or crash simulation k file. You can download entire foldable phone simulations, ballistic impact models, or MEMS devices. Study their keywords. That is a live, free tutorial.
