Following the successful launch of Duke Version 3.1 in December 2015, the IT’IS Foundation is pleased to announce the release of all ten Virtual Population cV3.1 models, which have now been upgraded with the new physics-based Poser method implemented in the multiphysics computational life sciences platform Sim4Life. Based on the high resolution Virtual Population V3.0 models, the method allows the posture of an anatomical model to be changed by implementation of biomechanical finite element method (FEM) simulations that treat the body as a deformable hyperelastic material with rigid bones. Further refinements in the skin tissue and a systematic separation of the bones of the feet are other distinguishing features of the latest version.
The segmentation of the cViP 3.1 models is exactly the same as that of Version 3.0, the previously available posable models, but the new models offer improved posing of several joints, volume preservation, and natural and intact stretching of the skin and underlying tissues, which is a fundamental requirement for accurate simulations of human anatomy. In addition, the new challenging postures that can be achieved extends the usability of the ViP models to a variety of novel scenarios, such as exposure evaluations of humans sitting inside a car or at a work place.
