The Electromagnetics (EM) module in LS-DYNA solves the Maxwell equations in the Eddy-Current approximation. The solver is coupled with the solid mechanics and thermal solvers of LS-DYNA allowing the simulation and solution of applications such as magnetic metal forming, welding, bending, induced heating, resistive heating and so forth. The course includes a presentation of the solver’s general principles, a complete description of the associated keywords as well as an introduction to the more advanced features (inductive heating problems, exterior magnetic field, magnetic materials). Key electromagnetic concepts are reviewed through­out the course. General knowledge about electromagnetics is appreciated, but not mandatory.

ICFD Incompressible Fluid Solver in LS-DYNA

Date:    5 - 6 October
Course fee:    1.100,- €*
Location:    Stuttgart
Lecturer:     Iñaki Çaldichoury (LSTC)
Registration

This course provides an introduction to the incompressible fluid solver (ICFD) in LS-DYNA. It 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 first day of the course includes a presentation of the general principles and applications of the solver, a step by step guide to setting up a simple CFD problem, advanced feature introduction (FSI, conjugate heat transfer) and so forth. The second day will deal with the newly implemented features and advanced applications. No expert knwoledge is required as there will be a brief review of basic fluid mechanics and CFD concepts.

Concrete and Geomaterial Modeling

Date: 6 - 7 October
Course fee: 1.100,- €*
Location: Stuttgart
Lecturer: Dr. Len Schwer (Schwer Consulting)
Registration

The course starts from the common ground of introductory metal plasti­city constitutive modeling and successively builds on this base adding the constitutive modeling features necessary to model concrete and geomaterials. The LS-DYNA constitutive models covered are adequate for modeling most types of rock, all kind of concrete, and a large class of soils. The course is intended for those new to concrete and geomaterial constitutive modeling, but will also be useful to those seeking a more in-depth explanation of the LS-DYNA concrete and geomaterial constitutive models covered.

CESE Compressible Fluid Solver in LS-DYNA

Date: 7 October     
Course fee: 550,- €*
Location: Stuttgart
Lecturer: Iñaki Çaldichoury (LSTC)
Registration

The new compressible flow solver CESE in LS-DYNA is based on a novel method that includes a unified treatment of space and time by the introduction of a conservation element (CE) and a solution element (SE), which allows for more accurate solutions of the shock waves than normal second order schemes. Attendees of this seminar will be given an introduction to apply this method for their simulations. So far, CESE 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 (FSI) problems with the embedded (immersed) boundary approach or moving (fitted) mesh approach.

Integrative Simulation of Short-/long Glass Fiber Reinforced Plastics with LS-DYNA

Date: 10 October (9:00 - 12:00)
Course fee: Free of charge
Location: Bamberg
Lecturer: 4a engineering / DYNAmore
Language: German
Registration

With fiber-reinforced plastics, the resulting fiber orientations in the molded component lead to many local anisotropies. To obtain accurate simulation results, these anisotropies should be incorporated in the structure simulation. One way to achieve this is by transferring the computed fiber orientations from a previous injection molding simulation to the structure simulation using a mapping program. The goal of this workshop is to present this integrative simulation approach in detail, to explain its advantages and to demonstrate a procedure to include micromechanics with the aid of an example. Furthermore, the possibilities of such material modeling using 4a impetus are shown and the approaches and possibilities of *MAT_157 and *MAT_215 are discussed.

NVH and Frequency Domain Analysis with LS-DYNA

Date: 13 - 14 October
Course fee: 1.100,- €*
Location: Stuttgart
Lecturer: Dr. Yun Huang (LSTC)

Registration

In this seminar, an overview is gi­ven on the acoustic and frequency do­main vibration features of LS-DYNA. It will particularly focus on the application of these features in vehicle NVH simulation. The seminar addresses engineers and resear­chers who are working in the area of vehicle NVH, air­craft/spacecraft vibro-acoustics, engine noise simulation, machine vibration testing and simulation, etc. All required knowledge to run these simulation problems with LS-DYNA will be presented in detail.

Meshfree EFG, SPG, Advanced FE Methods

Date: 13 - 14 October

Course fee: 1.100,- €*
Location: Stuttgart
Lecturer: Dr. Wei Hu (LSTC)
Registration

Attendees of this seminar will be introduced to the fundamental background of various Meshfree and advanced FEM methods. Particular attention is drawn to the application of the meshless method “Element-Free Galerkin” (EFG) as well as the newly developed method “Smoothed Particle Galerkin” (SPG). The seminar will thoroughly refer to the settings required in the LS-DYNA input deck to carry out a successful non­linear meshfree or advanced FEM simulation. Common applications of these methods are materials made of rubber or foam that undergo large deformations. The adaptive EFG formulation is the method of choice for the efficient simulation of cutting, bulk forming and forging processes.

Methods for Simulating Short Duration Events

Course fee: 1.100,- €*
Location: Stuttgart
Lecturers: Paul Du Bois (Consultant); Dr. Len Schwer (Schwer Consulting)
Registration

This two day class provides in­struction on the selection and use of the LS-DYNA solvers used for analyzing blast and penetration related problems. It addresses experienced LS-DYNA analysts of typical Lagrange analyses. The training class will provide additional tools and knowledge required to make appropriate modeling decisions and convey the level of confidence in predictive results. Insights into modeling and simulation are illustrated through examples and numerous modeling ‘tricks’ and options are discussed. An emphasis is placed on modeling techniques, guidelines for which technique(s) to select, which techniques work well and when, and possible pitfalls in modeling choice selections.

Blast Modeling with LS-DYNA

Date: 17 - 18 October
Course fee: 1.100,- €*
Location: Stuttgart
Lecturers: Paul Du Bois (Consultant); Dr. Len Schwer (Schwer Consulting)
Registration

LS-DYNA is unique in offering analysts the choice of Lagrange, Eulerian (ALE) and Simple Engineering solvers, and acombination of these solvers. For example for simulating high energy events such as blast loading.  In addition to air blast, the traditional focus of blast modeling has recently become important. This class focuses on the application of LS-DYNA for the simulation of high energy events. Methods of analysis and modeling are illustrated through case studies. However, this training class is not a substitute for the in-depth treatments presented in the associated LS-DYNA training class, i.e. “ALE/Eulerian and Fluid Structure Inter­action.”

LS-OPT – Introduction and Optimization

Date: 18 - 20 October
Course fee:  1.425,- €*
Location: Stuttgart
Lecturer:  Katharina Witowski (DYNAmore)
Registration

LS-OPT is an independent, compre­hensive optimization program from LSTC. It is ideal for solving strongly non-linear optimization pro­blems and is highly suitable for use in combination with ­LS-DYNA or any other solver. LS-OPT functions on the basis of a special, highly effective response surface method. The program also includes stochastic methods for assessing the robustness of FE models and illustrating dependencies between optimization variables and desired values. Input from the user is supported by a comfortable graphical user interface. The seminar gives an introduction to the program LS-OPT. General theoretical aspects of the Response Surface Method are discussed and the possibilities of applying this method in LS-OPT are especially explained.

Penetration Modeling with LS-DYNA

Date: 19 - 20 October

Course fee:    1.100,- €*
Location: Stuttgart
Lecturers:  Paul Du Bois (Consultant); Dr. Len Schwer (Schwer Consulting)
Registration

In addition to high energy events, penetration events are typically associated with large deformations, damage, and failure both on the material and structural level. During the past decade successful modeling of such damage and failure has moved steadily from a “Black Art” to a widely accepted engineering practice. This class focuses on the application of LS-DYNA and provides analysis methods and modeling techniques, which are illustrated through case studies. However, this training class is not a substitute for the in-depth treatments presented in the associated LS-DYNA training classes, i.e. “ALE/Eulerian and Fluid Structure Interaction” and “Smoothed Particle Hydrodynamics (SPH) in LS-DYNA”, respectively.
