Achieving a full human body positioning workflow in your LS-DYNA environment, utilising Oasys PRIMER

Arup

This workshop will demonstrate how to use Oasys PRIMER to position human body models for LS-DYNA.

Oasys PRIMER is used by over 50 companies world-wide to position a wide range of industry-leading THUMS and GHBMC human body models.  This workshop will demonstrate the full positioning workflow using real-world examples and highlight the latest positioning functions in Oasys software. It will also introduce top-tips and techniques to help the practicing engineer achieve realistic articulation of human body models.

Time will be available for Q&A and informal audience participation, providing opportunity for attendees to discuss and share any specific pain-points and challenges in their current CAE/LS-DYNA workflow.

This workshop is ideal for both existing Oasys PRIMER users and anyone interested in the growing topic of human body model injury prediction in LS-DYNA.

Further enhancing your pedestrian protection analysis through the Oasys LS-DYNA Environment

Arup

This workshop will demonstrate the latest capabilities of the Oasys LS-DYNA Environment software for assessing pedestrian protection in LS-DYNA.

The Oasys LS-DYNA Environment has been a pioneer of pedestrian protection assessment analysis for over 20 years. Tools have been developed in collaboration with in-house engineering teams working on live pedestrian protection projects. These tools help engineers power through their workflow, from vehicle mark-up and model build to automatic reporting and understanding results. This workshop will provide a comprehensive overview of all pedestrian analysis related tools using live demonstrations, highlighting new functionality in the latest software releases and support for the latest regulations, and providing an opportunity for questions and discussion about the topic and tools.

This workshop is ideal for anyone involved with the assessment of pedestrian protection using LS-DYNA.

Simulation Data Management with SCALE.sdm

The workshop gives an overview of the simulation data management environment SCALE.sdm. The framework consists of three modules:

--SCALE.project: Project administration, milestones, requirements, responsibilities, targets, approval,...

--SCALE.model: Model setup (CAD, mesh, simulation), version management, load cases, HPC-submit, documentation, collaboration,...

--SCALE.result: Evaluation of test and simulation results, assessment, reports, correlation, data analysis,...

The modules are known under the former names Status.E, LoCo and CAViT.

There will be a discussion on how to benefit from SCALE solutions from the perspective of a user and from the perspective of a project manager. Examples of typical CAE workflows and processes with SCALE.sdm are introduced within live demos. A lively discussion at the end of the workshop is very welcome to investigate a potential integration of SCALE.sdm software in your environment.
