Isight and Fiper 3.5 software let product-development engineers integrate cross-disciplinary models and applications together in simulation process flows, automate their execution across distributed compute resources, and explore the resulting design space. Isight 3.5 (formerly known as iSIGHT-FD) generates such flows by linking software including CAD, CAE, Microsoft Excel, and home-grown code. The software includes advanced engineering techniques such as optimization, Design for Six Sigma, approximation methods, and Design of Experiments. Fiper, an add-on module to Isight, lets users share multidisciplinary simulation results. Users can access Fiper directly from Isight or from a Web interface. For more information, visit
