About FE SET 50F and 50M

The FE SETs are Finite Element (FE) models of the Seat Evaluation Tools (SETs). The SETs were developed as part of the project VIRTUAL, with the aim of evaluating protective performance of vehicle seats in low velocity rear impacts.

The geometries of the two SETs represents the body shapes of the average (50th percentile) females (50F) and average males (50M) at 50 years of age, based on data from HumanShapetm. The same set of data was also the base for the VIVA+ 50F and 50M models1. The 0.1 version of the SETs can be downloaded from this repository and a detailed description of the consrtruction is published in Karemyr et al. (2022)2.

A beta version of the FE SETs3 were developed based on the CAD geometry of the 0.1 version of the SETs. An updated version of the FE SETs (based on SET v0.2), were released as FE SET v2.0.0 to this repository as on the 27th November 2025 in connection to the Carhs: Safe Seat Experience. See table below for version referencing.

Funding for the development and documentation of the FE SET models was provided by Swedish Transport Administration (Trafikverket), the Swedish National Road and Transport Research Institute (VTI) and the Swedish national research funding agency, Vinnova. All views, conclusions and methods presented here are the authors and do not necessarily present the views of the funding agencies.

The updates of the FE SET 50F from the beta version to version 2.0.0 was done with inhouse support from Toyota Motor Company, Japan.
