Breaking the Barriers to Realistic Simulation of the Human Body
Dr. Steve Levine
Living Heart Project at Dassault Systems, SIMULIA
It would be difficult to overestimate the impact on engineering, industry and society if we can accurately and cost effectively perform realistic simulations of the human body and its systems. In fact, understanding and replicating the physics of the human body seems poised to be the next major horizon for a growing range of simulation tools that have now become irreplaceable for developing products from microchips to jetliners. However, despite being the focus of countless studies over decades, it is not until recently has instrumentation been available to reveal its detailed dynamic behavior with sufficient accuracy to allow modeling and simulation to finally cross the threshold onto this frontier.
This presentation will highlight several areas of significant progress in virtual human simulation including the global translational cardiovascular initiative, the Living Heart Project. Through this project, a quantitatively accurate, fully coupled electromechanical simulation of a four chamber human heart was developed and made generally available in a robust commercial package. This computational model can provide critical insight to improve and develop new devices and procedures for treating heart conditions, the leading cause of death worldwide. Progress on musculoskeletal hybrid multiscale models will also be presented that consist of realistic 3D structures for deformable joints, ligaments and soft tissues using novel non-linear finite element workflows to isolate the force balance under true load conditions.
Applications examples will demonstrate the state-of-the art in replicating anatomically correct behavior at both the organ and musculoskeletal level using standard technology, representing a scalable translational environment for understanding human behavior in a real world context.
Bio:
Dr. Steve Levine is Sr. Director of Product Strategy and the Executive Director of the Living Heart Project at Dassault Systems SIMULIA. Since 2006, Steve has been responsible for driving the SIMULIA strategy towards its vision of enabling simulation to help harmonize Product, Nature and Life. Steve began his career at Engelhard Corporation, where he founded and led an applied simulation group in corporate R&D for over five years. In that time, his work featured in a number of discoveries, new product patents and he received several technical awards, including the highest research achievement award possible. Steve subsequently joined Biosym Technologies, a biomolecular simulation startup, which grew to become the leading modeling provider for the Pharmaceutical, Chemical, Materials industries, going public as Accelrys Inc. in 2003. Acclerys is now part of Dassault Systems creating the foundation for the brand BIOVIA. During his 15 years at Accelrys, he held a number of positions including Director of Product Development, GM of Materials Informatics, and Sr. Director of Corporate Development. Steve holds a Ph.D. in Materials Science and Engineering from Rutgers University and has been elected into the American Institute for Medical and Biological Engineering (AIMBE)'s College of Fellows.
