Welcome to LS-DYNA Examples


The site presents approximately 300 LS-DYNA examples from various training classes. The input files and several class notes are available for download. The download is free of charge, a login is not required. The majority of content  has been contributed by LSTC. All examples are presented with a brief description. You may find an example by checking a specific class or by using the search functionality of the site.

The content is prepared for educational purposes. Hence, material properties and other parameters might be non-physic for simplification.

If you are looking for an example containing some specific LS-DYNA keyword you may use the site search in the header section of this page.  …more

The examples in this section are from the ALE (Arbitrary Lagrangian Eulerian Method) class of M'hamed Souli. M'hamed Souli is Professor at the University in Lille France. The author is a key developer for the powerful capabilities of the Eulerian Methods in LS-DYNA. The examples run with LS-DYNA 970 and upwards.  …more

The *CESE keyword cards provide input for the Conservation Element/Solution Element (CESE) solver. This method is a novel numerical framework for conservation laws. It has many non-traditional features, including a unified treatment of space and time, the introduction of conservation element (CE) and solution element (SE), and a novel shock capturing strategy without using a Riemann solver. To date, this method has been used to solve many different types of flow problems, such as detonation waves, shock/acoustic wave interaction, cavitating flows, and chemical reaction flows. In LS-DYNA, it has been extended to also solve fluid-structure interaction problems with the embedded (or immersed) boundary approach or moving (or fitting) mesh approach.  …more

Connections are widely used in LS-DYNA models. These tutorials explore various connections including bolts, adhesives and spot welds. This tutorial will discuss various important factors in connection models including contact & material definitions, the types of elements used, and other potential techniques to use.  …more

The Discrete Element Method (DEM) is usually applied to predict the behavior of different types of granular media during mixing processes, storage and discharge or transportation on belts. Friction coefficients as well as spring and damper constants can be defined in normal and tangential direction. A continuum-mechanical description can be obtained with the introduction of “bonds” between the particles. Herein, the required mechanical behavior of the bonds is automatically computed by LS-DYNA using the parameters given in the material card.  …more

The *EM keyword cards provide input for a new electromagnetism module for solving 3D eddy-current, inductive heating or resistive heating problems, coupled with mechanical and thermal solvers. Typical applications include magnetic metal forming and welding. A boundary element method in the air is coupled to finite elements in the conductor in order to avoid meshing the air. For Eddy current related applications, you can follow this series of tutorial videos :  …more

Incompressible Computational Fluid Dynamics (ICFD) focuses on the solution of CFD problems, where the incompressibility constraint may be applied, e. g. ground vehicle, aerodynamics, hemodynamics, free-surface problems, ship hydrodynamics, etc. The solver may run as a stand-alone CFD solver, where only fluid dynamics effects are studied, or it can be coupled to the solid mechanics solver to study loosely or strongly coupled fluid-structure interaction (FSI) problems.  …more

The latest examples were presented at the 2017 Salzburg conference by George Laird. Other recent input files were provided by Alexander Gromer of DYNAmore (2016 Bamberg) and by Satish Pathy of LSTC. Most of the older examples are taken from the implicit classes of LSTC and were created by Prof. Dr. Ala Tabiei and Brad Maker. The copyright is with LSTC. You may check the examples separately with the menu on the left. For educational purposes the examples have to be modified to run properly. The description of the examples explains how to work with each example.  …more

The examples in this section are from the SPH (Smooth Particle Hydrodynamics) class of LSTC. You may access the examples separately by the menu on the left. The examples are prepared for LS-DYNA 970 and upwards.  …more

The examples in this section present the thermal capabilities of LS-DYNA. They are provided by Dr. Art Shapiro. Art is working since decades on topics reated to DYNA3D, LS-DYNA and TOPAZ. He is the key developer for the thermal capabilites of LS-DYNA. Art is one of the co-founders of LSTC. You may access the examples separately by using the menu on the left.  …more

The examples in this section are from the introductory class on metal forming from LSTC. You may access the examples separately by the menu on the left. The examples are prepared for LS-DYNA 970 and upwards.  …more

The examples in this section are from the 'LS-DYNA Examples Manual'. The manual was published by John D. Reid and LSTC in March 1998. The copyright is with LSTC. You may check the examples separately by using the menu on the left.  …more

This guide is mainly addressed to first-time users. Several of the problems present a closed-form solution, while others a reference solution obtained by using an arbitrary refined mesh (NAFEMS Benchmarks). Most of the problems are IMPLICIT ones.  …more
