About VIVA+ versions

  • This downloads the stable release v2.0.1. This version is currently certified for EuroNCAP CP550.
  • A minor update, v2.0.2, was released to fix element formatting and ensure compatibility with PIPER positioning. v2.0.2 can be downloaded from the main repository on OpenVT or by clicking here
  • If you are looking for v1.x, last version was 1.1.1 Download v1.1.1

Getting Started

Where do I find the model files?

In the folder model, the average-sized seated female model can be found in the subfolder 50F-seated. Similarly, the seated male and the standing female and male models is located in the same folder.

  • vivaplus-50F.key or similar is the main file.
  • The model is divided into multiple include files for modular file structuring. Most of these include files are located in the model/common/ subfolder and are shared between all the models - female and male, seated and standing. For more information on how the model definitions are organized, including the identifiers in the models, see the documentation on model structuring

Model Validation

The LS-Dyna simulation setups for the validation load cases are available for download on OpenVT: https://openvt.eu/fem/viva/vivaplus-validation/.

The validation responses can be viewed at the Validation section of this documentation.

WIP: Validation Catalog Transition

The validation catalog was previously hosted at https://vivaplus-validation.readthedocs.io/. We are in the process of integrating all validation reports into this documentation platform to provide a unified and streamlined experience. If you encounter missing content or discrepancies, please contact us so we can address them.

Certification for Virtual Testing

Find the reports for HBM4VT load cases run for Euro NCAP CP550 on the HBM4VT section of the documentation.

Open Source

VIVA+ Human Body Models are openly available under the LGPL v3 license . The models are hosted and maintained in an open repository on the OpenVT platform. Previous stable releases can be downloaded from Zenodo.

The models are available without restriction on reuse or modifications. If you wish to re-share, see guidelines and other information on the FAQs page (1). Learn more about our open science philosophy on the Open Science page(2).
