Generative Design in Solid Edge: Optimize Shapes to Achieve Design Goals
Siemens – Generative design in Solid Edge integrates advanced topology optimization within the Solid Edge 3D modeling toolkit, helping designers to create lighter components, minimize material waste in downstream manufacturing. Generative design produces an organic, reduced-mass geometric solution of a specific material optimized within a defined space, accounting for permissible loads and constraints.

These highly customized designs are well-suited for casting or high-resolution 3D printing, or they can be modified for traditional manufacturing. more (pdf)>

Updates from GE

These New Warships Will Be So Quiet, They Can Sneak Up On Submarines
By Tomas Kellner – The Royal Navy is working on a new high-tech Global Combat Ship designed to become the “workhorse of the fleet” and focus on a variety of maritime missions ranging from complex combat operations to counterpiracy and disaster relief.

BAE Systems, the prime contractor for the Type 26 program, has recently announced that the first three ships will use advanced electric propulsion motors and drive systems developed by GE Marine.

This tech is nothing that Lord Nelson would recognize. GE has deployed a team of noise and vibration specialists using special 3D modeling software to map the acoustic dynamics of the ship’s electric motors. They designed an electric propulsion system that is quiet but also powerful. It will give the ship the key advantage of being able to hunt submarines more effectively without being detected. more> http://goo.gl/C7aHqI

CAD’s New Age of Functionality

By Beth Stackpole – In the 2000s, CAD was in a rut. Sure, there were regular updates with lots of new power features, but the advances did little to attract or inspire new users beyond the traditional base of CAD jockeys. Other emerging design platforms like Product Lifecycle Management (PLM) and new Computer-Aided Engineering (CAE) tools grabbed the spotlight.

Lately, CAD has made a resurgence. Thanks to an array of new 3D modeling advances and, in some cases, a complete rethinking of how CAD functionality is delivered, we’re starting to see an exciting generation of new platforms. more> http://tinyurl.com/899fz7z

3D CAD Brings Battleships to Life

By Beth Stackpole – Donn McKinney has been obsessed with large battleships for more than 30 years. Now, thanks to his diligence and dexterity with 3D CAD software, he’s close to producing an operational replica of the USS Missouri.

The full-scale CAD model is then being used to produce a 1/32nd scale physical replica, which translates into a 28-foot-long steel ship that will feature the ship’s complete functionality, including radar and fully operational scaled weapons. McKinney is also working with partners who are providing stereolithography services to create realistic 3D fittings based on the SolidWorks model, as well as to add a voice command telemetry (VCT) system that will allow presenters to give full military orders to the vessel and receive an immediate response. more> http://is.gd/wGM41d

For Dassault, 3D Sketch Is a Natural

By Beth Stackpole РThanks to the influx of mobile tablets like the iPad, 2D sketch tools and industrial design capabilities are suddenly hot. So hot that Dassault Syst̬mes just added a new 3D sketch tool to its CAD and PLM lineup.

The idea beyond CATIA Natural Sketch is to let users more quickly transform 2D ideas into 3D realities as well as to explore design details and alternatives by sketching directly on existing 3D models. more> http://twurl.nl/pb45b4

Mars‘ Newton Crater
NASA – This image, which combines orbital imagery with 3-D modeling, shows flows that appear in spring and summer on a slope inside Mars’ Newton Crater. Sequences of observations recording the seasonal changes at this site and a few others with similar flows might be evidence of salty liquid water active on Mars today. Evidence for that possible interpretation is presented in a report by McEwen et al. in the Aug. 5, 2011, edition of Science.

This image has been reprojected to show a view of a slope as it would be seen from a helicopter inside the crater, with a synthetic Mars-like sky. The source observation was made May 30, 2011, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter. Color has been enhanced. The season was summer at the location, 41.6 degrees south latitude, 202.3 degrees east longitude.

The flow features are narrow (one-half to five yards or meters wide), relatively dark markings on steep (25 to 40 degree) slopes at several southern hemisphere locations. Repeat imaging by HiRISE shows the features appear and incrementally grow during warm seasons and fade in cold seasons. Image Credit: NASA/JPL-Caltech/Univ. of Arizona
