Siemens PLM named Robert R. Ryan CEO of its CD-adapco subsidiary, whose president, CEO and cofounder, Steve MacDonald, passed away a few months before its acquisition by Siemens early this year. Ryan’s appointment puts a seasoned, world-class CAE executive at the helm of Siemens PLM’s CFD business. Ryan’s previous positions include chairman and CEO of ADAMS developer Mechanical Dynamics, Inc., acquired by MSC Software in 2002. Ryan’s appointment also strengthens confidence that the HEEDS multidisciplinary design exploration software from Red Cedar Technology—a CD-adapco subsidiary of which Ryan was CEO, and which Siemens PLM acquired in its CD-adapco purchase—will continue to receive proper resources, attention and management support.

The high-speed train market in recently industrialized countries is one of the most hotly contested engineered-product markets in the world, with even the smallest advantage important in gaining a competitive edge. In particular, fuel consumption is a critical factor in design, sales and maintenance of these vehicles. In this project, a manufacturer of high-speed rail vehicles needed to maximize efficiency, reduce emissions and decrease design time.
Seeking a more efficient engineering approach that would let it maximize the number of designs that could be tested within the project schedule, the manufacturer selected Sculptor from Optimal Solutions Software. By specifying key design parameters, the software allows hundreds of designs to be generated in a matter of minutes—a radical improvement over the company’s previous process, in which this phase of the project took months.

Design space exploration is both a class of quantitative methods and a category of software tools for systematically and automatically exploring very large numbers of design alternatives and identifying those with the most optimal performance parameters. The mathematical techniques that underpin design space exploration have been long known—and sometimes applied, in cases where the attendant costs in expertise, time and labor could be justified. What’s changing now is the way fresh software technologies are at last converting these powerful but formerly difficult-to-use methods into practical everyday engineering aids. Continue reading
Design optimization is the search for a structural design that is optimal in one or more respects. In all the various methods available for optimization, the design is guided to satisfy operating limits imposed on the response of the structure, and by further limits on the values that the structural parameters can assume. The power of numerical optimization is its ability to rationally and rapidly search through alternatives for the best possible design(s). Continue reading
Automating the search for solutions to engineering problems can take either of two broad approaches: design exploration or design optimization. Practitioners making technology choices need to understand which tools do one, which do the other, and which approach best fits their needs. A global roster of commercially available design exploration and optimization software appears at the end of this post. Continue reading
