Executive Letter
Advancing Simulation Technology and Methods—Together


t occurred to me, while listening to the GeneralLectures at our 2011 international SIMULIA Customer Conference in Barcelona, just how far we have come in the development of new and innovative analysis technology in Abaqus. A slew of advances such as Topology Optimzation, CFD, Electromagnetics, Smoothed Particle Hydrodynamics, GPU support, XFEM and so much more (page 17) have been delivered even as we have expanded our entire solution portfolioto include Isight, the SIMULIA Execution Engine, and Simulation Lifecycle Management (page 16). Most intriguing though was the first glimpse of ExSight, our next generation analysis products built on the Dassault Systemes Version6 platform, which will offer unprecedented integration of Abaqus and Isight technology in an intuitive, collaborative and managed environment.

The highlight of the 2011 SCC though was the 95 customer papers illustrating the breadth of the application of our analysis, process automation and optimization technology to explore and improve the performance of materials and products. The first keynote speaker, J. (Siva) Sivakumar, the Engineering Group Manager for General Motors Powertrain, set the stage for theconference by pointing out that— although CAE vendors have made vast improvements in simulation software over the years—it is ultimately the users that are at the heart of driving realistic simulation technology forward and making it an invaluable tool in the product development process. Anita Bestelmeyer, CAE Manager for BD, opened the conference on day two. She illustrated the positive impact...
