Accompanying seminars

In the week before and after the Forum, we offer our conference-accompanying seminars in Bamberg and Stuttgart, as always.

Simulating Short Duration Events

Date: October 4-5, 2022
Fee: 1200,- Euro*
Place: Stuttgart
Speakers: Paul Du Bois, Len Schwer
Course language: English
Registration

Most applications of LS-DYNA are for complex, and often combined, physics where nonlinearities due to large deformations and material response, including failure, are the norm. Often the goal of such simulations is to provide predictions which will ultimately be used to guide product development and safety assessments.

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. Simulation credibility is demonstrated through solution of multiple models, with associated multiple solvers, required checks of global and local energies, and mesh refinement strategies.

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 is intended for the LS-DYNA analysts possessing a comfortable command of the LS-DYNA keywords and options associated with typical Lagrange analyses. The training class will attempt to provide the analyst with the additional tools and knowledge required to make appropriate modeling decisions and convey the level of confidence in predictive results.

Blast Modeling

Date: October 6-7, 2022
Fee: 1200,- Euro*
Place: Stuttgart
Speakers: Paul Du Bois, Len Schwer
Course language: English
Registration

Blast events form a class of simulation environments well suited to the solution capabilities of LS-DYNA. LS-DYNA is unique in offering the analyst the choice of Lagrange, Eulerian (ALE) and Simple Engineering solvers, and combinations of these solvers, for simulating high energy events such as blast loading. In addition to air blast, the traditional focus of blast modeling, buried explosive charges have recently become important in the design of troop transportation.

This class focuses on the application of LS-DYNA for the simulation of high energy events. The analysis methods, and modeling, are illustrated through case studies. An emphasis is placed on modeling techniques: guidelines for which technique(s) to select, insights into which techniques work well and when, and possible pitfalls in modeling choice selections.

Sufficient mathematical theory is presented for each technique to provide the typical user with adequate knowledge to confidently apply the appropriate analysis technique. 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 & Fluid Structure Interaction.”

ICFD Incompressible Fluid Solver

Date: October 6-7, 2022
Fee: 1200,- Euro*
Place: Stuttgart
Speakers: Iñaki Çaldichoury (Ansys/LST LLC)
Course language: English
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 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.

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. A brief review of basic fluid mechanics and CFD concepts are also offered such that no expert knowledge of fluids is required. The second day will deal with the newly implemented features and advanced applications.

Resistive Heating and Battery Modeling

Date: October 13, 2022
Fee: 600,- Euro*
Place: Bamberg
Speakers: Iñaki Çaldichoury (Ansys/LST LLC)
Course language: English
Registration

This course is based on the Electromagnetics (EM) solver of LS-DYNA. The EM module computes the Maxwell equations and is embedded into LS-DYNA following LSTCs one-code strategy, thereby allowing for an efficiently coupling to the solid-mechanics and the thermal solver.

The seminar presents the solver’s general principles, a complete keyword description for setting up simulation models, on the one hand, to compute inductive and resistive heating problems. On the other hand, the modelling of batteries is addressed. Thereby exploiting the Randles-circuit approach to describe the charging and discharging process as well as the accompanying heat production.

NVH, Frequency Domain, Fatigue

Date: October 13, 2022
Fee: 600,- Euro*
Place: Bamberg
Speakers: Yun Huang (Ansys/LST LLC)
Course language: English
Registration

The objective of the training course is to introduce the frequency domain vibration, fatigue and acoustic features of LS-DYNA to users, and give a detailed look at the application of these features in vehicle NVH simulation.

This course is recommended for engineers who want to run NVH or other frequency domain vibra­tion, fatigue and acoustic simulation problems with LS-DYNA. This course is useful for 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.

Introduction to SPG Method for Manufacturing and Material Failure Analysis

Date: October 13, 2022
Fee: 600,- Euro*
Place: Bamberg
Speakers: Youcai Wu (Ansys/LST LLC)
Course language: English
Registration

This one-day class will introduce the smoothed particle Galerkin (SPG) method and its application in manufacturing and material failure analysis. The SPG method is developed for modeling large deformation and material failure in semi-brittle and ductile materials in three-dimensional solid structures, in which a bond-based failure mechanism is utilized to model material failure. This method can be used to bridge the Lagrangian FEM and is exclusively available in LS-DYNA.

The class will provide the fundamental background, LS-DYNA keywords, practical applications (in analyzing relatively low speed manufacturing processes such as metal cutting, FDS, SPR and high velocity impact penetration on concrete and metal targets) with some experimental validations and latest developments.

Electromagnetism in LS-DYNA

Date: October 14, 2022
Fee: 600,- Euro*
Place: Stuttgart
Speakers: Iñaki Çaldichoury (Ansys/LST LLC)
Course language: English
Registration

This course provides an introduction to the Electromagnetics (EM) solver in LS-DYNA. The Maxwell equations are solved in the Eddy-Current approximation suitable for cases, where the propagation of electromagnetic waves in air (or vacuum) can be considered as instantaneous. 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 and applications, a complete keyword description for setting up an Eddy-Current problem, an introduction to the more advanced features (Inductive heating problems, exterior magnetic field, magnetic materials and so forth) as well as an advanced description of the available controlling tools to ensure a safe analysis.

Key electromagnetic concepts are reviewed throughout the course and a general knowledge about electromagnetics is therefore appreciated but not mandatory.
