ALE and Fluid/Structure
Coupling in Ansys LS-DYNA

Course Overview

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.


  • You should be familiar with Ansys LS-DYNA.

Target Audience

Structural, thermal and fluids engineers primarily in Aerospace, Automotive, Health care, food and defense industries.

Teaching Method

Lectures and computer practical sessions to validate acquired knowledge.

Learning Outcome

Following completion of this course, you will be able to:

  • Learn Equations of state and Material models used in ALE.
  • Accurately model fluid behavior.
  • Understand differences between Eulerian and ALE.
  • Learn how to set up coupling with structure.
  • Control leak in FSI.
  • Reduce analysis time by controlling ALE domain shape.
