What's growing faster, simulation software (FEA and CFD) or CAD? Research and analysis firm Daratech says it's simulation. "It's not just for experts and mathematicians anymore," says Daratech spokesman Tim Hickey. Engineers in every industry are seeing the benefits of cutting the number of prototypes they smash into walls to test for stress. Simulation helps by letting them smash the designs on the computer. That democratization of simulation has led to a brisk business for companies that teach FEA and CFD or, like Daratech, build conferences around it. In June, Daratech held a simulation conference that centered on the automotive industry and drew 260 participants—30 more than the same conference the previous year. On November 3, Daratech will kick off its aerospace and defense simulation conference in Anaheim's Disney Paradise Pier Hotel and organizers are expecting a similarly robust crowd. Among the session topics: Digital product simulation, as well as high-performance compacting for engineering modeling & simulation, analysis, and test & measurement. Presenters include representatives from MSC.Software, ANSYS, Abaqus, Hewlett-Packard, Silicon Graphics, EDS PLM Solutions, Engineous, and Synops, among others.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
