Engineering simulation is the next big thing in medical development. It can be used to design, rethink and optimize devices before going into clinical trials. These simulations can also be used as an invaluable tool in determining which surgical technique is best to use on a specific patient. Additionally, it allows scientists and physicians to  predict the route of a drug through the body. Because it only involves the calculating power of a computer, it is a fast and cheap alternative providing an enormous competitive advantage for the companies that use it. We spoke with Thierry Marchal, Global Industry Director for healthcare at ANSYS, a world leader in this technology, about this exciting revolution.
