FeatureScript amps up power of Onshape

Full-cloud CAD pioneer Onshape amped up the power and utility of its software with FeatureScript, a new programming language that lets users create new parametric features that look, feel and behave just like Onshape’s built-in features.

This is the same language used by Onshape itself to develop all of its software’s current features—Extrude, Fillet, Shell, Loft and the like. Now available as an open language, FeatureScript lets users create their own built-in parametric features in Onshape.

Under the open-source MIT License, Onshape is also sharing the FeatureScript source code for all of its own features, allowing customers to copy, modify or adapt them as they see fit. New features can be created, and existing features edited, in Onshape’s new Feature Studio, a user-friendly development environment with an editor, in-line help and documentation. Continue reading

Noesis Solutions High-Performance Computing for Surf Bums webinar

Noesis Solutions High-Performance Computing for Surf Bums webinar, August 31, 4:00 am, 9:00 am & 2:00 pm ET. Webinar attendees will learn how to: (1) create an easy-to-use custom application within a familiar tool like Microsoft Excel that makes the magical world of simulation easily accessible to non-specialists for the design of surf boards. Through this application, they will have access to a full range of advanced modeling and simulation tools (Sculptor, OpenFOAM, ParaView & Optimus) and will be able to run them within the scope that the specialist defines within his custom application; (2) hide all the engineering complexity from the target user, but provide him with a full range of reporting tools within Microsoft Excel such that it becomes clear at first glance how the surf board design can be improved and optimized; (3) speed up simulation throughput by connecting the application to the full power of the Microsoft Azure Cloud Computing Platform—all of this completely transparent to the user.

Structural components made of glass-fiber reinforced plastic (GFRP) fabricated into complex-profile linear shapes are widely used today in aerospace, civil infrastructure and other industries. Examples include aircraft structural components, elements of power line support structures, and bridge structural elements such as beams, decking and girders. Although somewhat more expensive than comparable components made of traditional materials such as metals, concrete or wood, polymer composite structures can have decisive advantages over their traditional counterparts, especially where weight or corrosion resistance is critical.

However, they still need to be cost-effective. One way to achieve this is by taking advantage of GFRP’s ability to be fabricated into large integral structures with lower production costs than counterparts made of traditional materials. While feasible and already applied in various industries today, this approach requires sound understanding and control of the fabrication process to avoid process-induced shape deformations. When the dimensions of finished items fall outside specified limits, misfits or clashes result when assembling components of complex structures.

The challenges of fabricating GFRP components within specified dimensional tolerances have conventionally been solved experimentally, through trial-and-error variation of process parameters during fabrication. This iterative procedure is expensive, labor-intensive and, above all, not very effective, especially when fabricating large components. Thus, industries that rely on GFRP components have an urgent need for mathematical models that effectively predict process-induced residual stresses and deformations, and reveal how to improve and optimize the fabrication process.

Siemens PLM appoints Bob Ryan CEO of CD-adapco

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.

System-level physical modeling and simulation: Research background, objectives, methodology

Discussions of how to bring simulation to bear starting in the early stages of product development have become commonplace today. Driving these discussions, we believe, is growing recognition that engineering design in general, and conceptual and preliminary engineering in particular, face unprecedented pressures to move beyond the intuition-based, guess-and-correct methods that have long dominated product development practices in discrete manufacturing. To continue meeting their enterprises’ strategic business imperatives, engineering organizations must move more deeply into applying all the capabilities for systematic, rational, rapid design development, exploration and optimization available from today’s simulation software technologies.
