STEM Provides Roots and Growth

Thursday, September 28th, 2017

A debate continues to rage about America’s general decline in science, engineering, and technology, largely blamed on the first steps of our youngest citizens – math and literacy education.

A couple of years ago I taught math to middle and high school students and witnessed firsthand not only the challenges, but also the opportunities for positive change brought about by a belief and commitment to teaching.

From my perspective, I learned that I taught to overcome two different but related needs – innumeracy (unfamiliarity with mathematical concepts and methods and the inability to use mathematics) as well as illiteracy (the inability to read and write). They both go hand in hand, because as important as getting the numbers right is, the ability to provide a convincing argument and communicate the numerical answer of the “why and how” is just as important.

Quality Information Framework: The Digital Thread For Interoperability

Thursday, September 21st, 2017

Interoperability, collaboration, inspection, quality, standards, proprietary data, neutrality, competition, and innovation. Over the years there have been myriad attempts to bring these processes together, all while protecting IP. However, as we know, while the attempts to make this happen have often been valiant, too often they have fallen well short, or worse, failed altogether.

That legacy of failure is on its way to being a thing of the past with the advent of the Quality Information Framework (QIF), an ANSI standard that supports digital thread concepts in engineering applications ranging from product design through manufacturing. Based on the XML standard, it contains a Library of XML Schema ensuring both data integrity and data interoperability in Model Based Enterprise (MBE) implementations.

QIF supports design, metrology, manufacturing, and is critical to the Industrial Revolution 4.0. Because it is XML based, QIF can be relatively easily integrated with Internet applications, and unlike other existing standards, there is no real barrier standing in the way for industry adopting QIF. It also effectively supports newer technologies, including additive manufacturing and the Internet of Things (IoT).

First Look At SOLIDWORKS 2018

Thursday, September 14th, 2017

Well, another Labor Day has come and gone, and summer is almost over, but that means that a new version of SOLIDWORKS is about to launch. It actually and officially launched earlier this week.

I spoke with Kishore Boyalakuntla, SOLIDWORKS Vice President, Portfolio Management and Brand UX Leader about what was new in SOLIDWORKS 2018, and there was a lot to cover. Keep in mind, though, that I’ll just be touching on what I consider to be the highlights in SOLIDWORKS 2018 this time around. In the coming weeks and months I’ll be going into much more detail on the new version’s features and capabilities

Design To Smart Manufacturing

This time around, SOLIDWORKS says its design-to-manufacturing process provides the tools needed to implement a comprehensive design-through-manufacturing strategy, all inside the SOLIDWORKS environment. These tools let you work without having to export and import data from one system to another. With IP embedded in the 3D design model, and at the center of the model-based definition (MBD) process,, and thanks to associativity, changes from design or manufacturing are automatically reflected in all related CAD models, CAM programs, drawings, and documentation.

Additionally, all the information for manufacturing, inspection, and simulation and verification is directly linked to the design, so it always reflects the current design iteration (which is always a good thing).

ANSYS Discovery Live Accelerates Engineering Simulation For Concept Exploration

Thursday, September 7th, 2017

Even though we’ve been told by a number of software vendors for several years now to use engineering simulation and analysis at the earliest stages of product development, relatively few companies have heeded the advice and actually done so. In many cases, it’s still design, break, repeat in a cycle that gets very expensive quickly trying to achieve optimized design goals. Even with all the insistence and chiding from the simulation folks, I’d estimate the percentage of design work that includes simulation early in the process as somewhere between 20-25%, although that may be a bit on the high side.

This week, ANSYS presented a technology preview of what it hopes will break and change that cycle with what it calls ANSYS Discovery Live .

 

With it, engineers can rapidly explore design options and receive accurate simulation results with technology using engineering simulation to make digital exploration available to all engineers so they can design better products faster and more economically.

That’s a pretty confident and heady statement, knowing that several other vendors have attempted the roughly same thing with widely varying degrees of success. However, ANSYS has an interesting and innovative approach for reaching its goal — exploiting GPUs because they can handle massively parallel operations.

ANSYS readily admits that while Discovery Live is a means of bringing simulation to the engineering masses earlier in the development process, it doesn’t pretend to do everything for everybody, and there will always be a place for engineering simulation specialists for deeper dives. Discovery Live is targeted to early design exploration and to users new to simulation. Because it is not a solution for every simulation problem, Discovery Live does not compete with other more advanced ANSYS products, such as AIM, but data from it can be exported for more further study.
