Finite Element Human Body Models for Injury Assessment

VIVA+ is a line-up of finite element human body models of vehicle occupants and standing road users, developed for LS-DYNA explicit solvers. The baseline model is an average female (50F). Three other models are maintained alongside it: average male (50M), standing average female, and standing average male.

Why VIVA+¶

Where to start¶

Validation¶

The validation cases are listed with the body region they cover, and the whole-body cases under Whole Body. The LS-DYNA setups and the postprocessing notebooks for every case are in the documentation repository.
