components and in aerospace for mission-critical components used in aircraft jet engines and airframe components. Other major applications are in medi- cal device design and for planning medical surgical procedures and for stress tests in building and bridge construction.


Embedded FEA in CAD/CAM systems has become more common recently, as FEA de- velopers offer more versions of the tools available to non-expert users. This trend of “democratizing” FEA simulation tools also has been enabled by the faster multicore processors of today that allow running the complex simula- tions on typical desktop or laptop computers. With FEA tools, many manufac- turers also are able to cut down on the number of physical prototypes needed for testing. Companies like General Motors have eliminated prototypes for iterative develop- ment testing, said Keith Meintjes, practice manager, Simulation and Analysis, CIMdata Inc. (Ann Arbor, MI). “The development iterations are the evil prototypes you want to rid of,” Meintjes said. “They’re the ones that are expensive, and there are all kinds of issues because they’re hand-built.” A key trend today is that customers expect their suppliers to bring more capability to the table in terms of their engineering expertise, and the types of tools that they bring to bear to solve problems, noted Ed Martin, senior industry manager, Manufacturing


Industry Group, Autodesk. “There’s a need for com- panies to be able to perform these analyses as these analyses get more complex. The amount of com- puting power that it takes to execute some of these very large Moldflow simulations can be substantial,” Martin said. Moving these simulations to the cloud offloads that from a manufacturer’s own systems,
