Optimize at the ESTECO Conference Nov. 6

The third annual modeFRONTIER 2013 Users Meeting is being held November 6 at The Inn at St. John’s, in Plymouth, MI. It is a place where users of modeFRONTIER, ESTECO’s platform for multi-disciplinary and multi-objective optimization, come together to exchange knowledge, share methods and techniques, and hear about other innovative experiences enabled by the software.

SolidThinking Inspire 9.5 Adds Stiffness Optimization, Deflection Control, Violation Explanation, and More

Optimization exercises are driven by input parameters — your inputs.  If you want the software to come up with the best possible shape build with the least amount of plastic to withstand a certain force, you need to tell the software what that force is. And that can be a stumbling block for some users, especially if they’re not simulation experts, or if the design is still at an experimental concept phase. Just to start off the process, the user might plug in a safety factor that seems reasonable. Then the software crashes. Or it displays the dreaded exclamation point embedded in a yellow triangle (software speak for “You’ve messed up!).

The frustrating part about this process is, you can’t communicate with the software. You can’t initiate a postmortem analysis, like you would with a real person, by asking, “Why can’t you compute that scenario? What happened?” It behooves you to know, because in that unexplained failure is a nugget of wisdom that may reveal something about your design’s weakness.

In Altair’s SolidThinking Inspire 9.5, when computation fails during an optimization session, you’d have the option to open up the Violation Table and inspect several columns of listed reasons. If you have entered a safety factor that the design cannot physically accommodate (perhaps because there just isn’t enough materials to trim to get to the desired results), you’ll know. That’s one of the improvements included in the new version of Inspire, Altair’s optimization software targeting designers. →']);" class="more-link">Continue reading

Dassault Systemes Snatches Up FE-Design, Gets into the Optimization Craze

 

FE-DESIGN GmbH, a German company with a product line named after a famous Italian opera, is going to become part of Dassault Systemes (DS), a French 3D software giant.

Today, in a transaction of undisclosed amount, DS acquired the Germany software maker known for its optimization packages: TOSCA Fluid and TOSCA Structure. DS already has a robust collection of simulation products, marketed under the SIMULIA brand. By acquiring FE-DESIGN, DS is boosting its current simulation offerings with the optimization technology in FE-DESIGN’s TOSCA products. →']);" class="more-link">Continue reading

DARPA’s FANG Challenge Showcases New Set of Design Tools

As DARPA gets ready to kick off the first of three FANG (Fast, Adaptable, Next-Generation Ground Vehicle) Challenges next month, the engineering community at large is closer to being able to test drive META, a new set of design tools that promise to fundamentally change the process of complex systems design. →']);" class="more-link">Continue reading

A New Way to Reduce Weight with NX 8.5

The diet industry and the computer-aided engineering (CAE) segment are heading for a head-on collision, at least in their terminologies. They both share a similar objective too: Like Jenny Craig and WeightWatchers, CAE software programs are now on a quest to help you lose weight. To be precise, more and more of these software are introducing ways to help you shave off materials, or excess weight, from your design. (For more, see “The Twin Forces of Optimization & Inspiration” in December 2012 issue, now available online.) →']);" class="more-link">Continue reading
