Abstract: This paper presents a comprehensive human modelling and simulation environment. This environment, called Santos, is a new generation of digital human simulation systems that allows a user to interact with a digital character with full and accurate biomechanics and a complete muscular system, subject to the laws of physics. Major results in the areas of dynamic motion prediction, advanced posture prediction and comfort level assessment, physiology model, modelling of clothing and muscle wrapping and force assessment will be presented. This paper will feature the various modules that comprise the Santos environment.

Keywords: digital human modelling; physics-based models; simulation; optimisation; vehicle design; biomechanics; dynamic motion prediction; advanced posture prediction; comfort level assessment; physiology modelling; clothing models; muscle wrapping; force assessment.
