Oasys PRIMER Workshop – Introduction and Demonstration of Automotive Tools – Gavin Newlands (Arup/Oasys)

Oasys PRIMER is used worldwide to pre-process LS-DYNA models. As well as the core tools for model creation and checking. PRIMER contains many tools to make it easier to setup automotive models/loadcases. This workshop will introduce these tools and demonstrate how to use them. Examples include:

• Barrier positioning
• Pedestrian protection
• Interior head impact
• Seatbelt anchorage
• Occupant setup
• Automation

ANSA and META: Crash and Safety at its best

BETA CAE Systems

ANSA and META offer a complete suite for Crash and Safety applications.

Seats are moved easily to the desired position and dummies are positioned on them, achieving a penetration free and restrained, by seatbelts, system. Occupant Injury criteria for simulation and laboratory tests can be easily evaluated in META.

Pedestrian analysts have at their disposal a complete tool for marking, bulk positioning and loadcase creation for all desired targets and post processing capabilities for the evaluation of the corresponding results.

All interior safety regulations available in the market are applicable in ANSA and META through automated tools for the safety of the driver and passengers.

Solution Explorer in LS-PrePost – a GUI for Nonlinear Implicit FE

T. Borrvall (DYNAmore Nordic)

The evolvement of multiphysics capabilities in LS-DYNA has made it a very powerful, albeit somewhat complicated, simulation product. To this end, the Solution Explorer was introduced to simplify modeling setup in fluid mechanics, and this has now been complemented with a framework for nonlinear implicit mechanics.

The vision of the Solution Explorer is to combine simplicity and power in an integrated pre- and post-environment, and this workshop presents its current state. We cover pre- and post-processing for single and multiple cases, in hope that it will provide a clear picture of its future potential.

Leveraging LS-DYNA Explicit and Implicit on Latest Intel Technologies

Phase Transformation of Metallic Materials

M. Merten, T. Klöppel (DYNAmore)

Several phase change models inLS-DYNA provide the possibility to numerically predict the distribution of process dependent material properties. The workshop gives a brief overview on existing models and discusses the recently developed material *MAT_254 in some detail. Possible approaches to calibrate this complex material model based on given experimental results are shown. In a first example, an isothermal TTT-Diagram is used
to define a material card for the press hardening steel 22MnB5. A second show case demonstrates the potential application of the material model to the ‘bake hardening’ effect of 6xxx aluminium alloys.

Simulation Data Management with SCALE products

M. Thiele (SCALE)

The workshop gives an overview of the SCALE SDM products such as LoCo, CAViT and Status.E.

There will be a discussion on how to benefit from SCALE solutions as a user or project manager. The application of selected uses cases will be presented within live demos. Examples of typical CAE workflows and process automation using SCALE SDM applications are introduced.

A lively discussion at the end of the workshop is very welcome to investigate a potential integration of SDM software in your environment.
