Human Body Fe Model Repositioning: a Step towards Posture Specific – Human Body Models (ps-hbm)

This study reports a methodology to generate anatomically correct postures of existing human body finite element models while maintaining their mesh quality. The developed method is based on computer graphics techniques and permits control over the bone kinematics followed. Initial mesh quality of the model being repositioned is quantified and maintained during the process in order to preserve the suitability of the model for subsequent use. For some critical areas (soft tissues around knee joint like capsule, menisci) where element distortion is large, mesh smoothing technique is used to improve the mesh quality. The tool developed repositions a given lower extremity model (knee joint) in just a few seconds.
