The use of simulation in engineering is shifting from sequential (one at a time) to parallel (many at a time, running simultaneously on high-performance computing systems). The move is precipitated largely by optimization and lightweighting, which require evaluating a series of design options or families of designs to identify the best candidates.
But this adds a new dimension to simulation. Now, you need a way to view the results — the best ones, as identified by the software’s algorithm — in a comprehensible fashion to understand the correlations between different parameters and the geometry. For example, what happens to the aerodynamic performances of the vehicle when you increase the curvature of the hood by a certain degree? Or how does the position of the side mirrors affect the car’s drag? →']);" class="more-link">Continue reading
A week after OTOY announced the launch of its app-streaming platform X.IO, NaviSite, a cloud service and product vendor, is launching Desktop-as-a-Service (DaaS) products, powered by NVIDIA GRID. NaviSite believes the product beings “desktop virtualization for even the most intensive graphics workloads to a broader audience of end-users using engineering, design, and multimedia applications.”
Though underlying technologies, acronyms, and definitions may be different, app streaming and DaaS are driven by the recognition that consumers are open to the idea of using remotely accessible workstations, billable for usage or time. With NVIDIA Grid, NaviSite’s DaaS offers remote desktops with GPU acceleration, a characteristic that’ll be important to CAD and design software users who rely on photorealistic visuals to evaluate product aesthetics. Since most of the computing is done on the hosted hardware, users may interact with the remote machine from a lightweight tablet or PC, usually priced far less than a professional workstation. →']);" class="more-link">Continue reading
Even though CadSoftTools calls its software ABViewer, the program is more than a file viewer. Now in its 10th release, ABViewer has a robust authoring environment (the Editor tab) with drawing tools to create detailed drawings from scratch. The crosshair mouse pointer, command line, polyline tools, layering system, and line and text property controls offer a setup that feels familiar to those accustomed to AutoCAD or AutoCAD LT.
In the viewing mode (the Viewer tab), the program supports neutral formats, including STL, IGES, DWG, DXF, and PDF. With detailed DWG files and neutral 3D files, the program’s performance is quite good. The structure window (positioned on the right corner of the viewport by default) gives you a way to turn off or on certain elements and view your assembly components in isolation or together. Measurement tools allow you to select a face and get information on the region, or take your own measure between points with a virtual ruler. Different viewing options let you view the 3D model in shaded mode, wireframe mode, with smooth shading, or with hidden lines. →']);" class="more-link">Continue reading
The growing popularity of 3D printing among the hobbyists as well as professional designers suggests a comparable rise in the use of reality-capture devices — hardware that lets you scan and capture the shape and geometry of physical objects. With 3D printers, Microsoft is betting the consumer models will pave the way for costlier, bigger professional models. (For more, read “Microsoft Adding Plut-and-Play 3D Printing to Windows OS,” May 7, 2014.) There’s good reason to make a similar assumption about 3D scanners as well.
Priced $399, the Cubify Sense seems ready to capture not just geometry but also the attention of early adopters and curious tech users. Measuring roughly 7 x 5 x 1 inches, the 3D scanner is smaller and lighter than a typical hardcover book. The device has no independent power source. It operates through a USB connection to a tablet or computer. The computer is also required for downloading the Sense software to activate and drive the device. Since whatever you want to scan may not be located close to your desktop, a laptop or a mobile tablet you can carry around is the best option for operating the scanner. →']);" class="more-link">Continue reading
Are the upcoming Corporate Average Fuel Economy (CAFE) standards realistic or achievable? It’s something EPA has to first find out for itself. To do that, the Agency is using ANSYS FORTÉ, a package for simulating combustion engine activities.
According to the announcement released by ANSYS today, EPA plans to use FORTÉ software “to model in-cylinder combustion to develop an advanced test engine that will demonstrate fuel-saving and emissions-reducing technologies.”
ANSYS FORTÉ used to be a product of Reaction Design, based on San Diego, California. The product became part of the ANSYS portfolio when Reaction Design was acquired by ANSYS this January. →']);" class="more-link">Continue reading
