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.

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.
