How to Make Smart Digital Twins

digital twins dynardoDigital twins continue to grow in importance. Here in Germany, engineers at many companies, including Bosch and Daimler, are dealing with complex applications and the challenge to improve the product performance to come up with an optimized and robust virtual design. They need to determine and evaluate the robustness of virtual prototypes, considering scattering effects, which is difficult or not even possible in hardware tests. Software is used to accurately and rapidly generate proper samples and the resulting understanding saves them a lot of time and money in prototyping so they can stay competitive. Continue reading

BorgWarner Goes Full Speed with ANSYS HPC Parametric Packs

It doesn’t matter what car you drive — it could be a snazzy Ferrari or a humble FIAT Punto — ultimately what we’re all looking for is a car that performs well and maybe saves us a little money at the pump.

The upcoming joint ANSYS-ESTECO webinar on September 15th will discuss just how important a single component, in this case, a tensioner arm, can be. Chain tensioner arms may not be as well known as pistons and gearboxes, but, by maintaining the correct amount of tension on the chain at all times throughout its duty cycle, they are important for reliable operation of the accessory chain drive system. The chain tensioner also helps protect other components, such as the alternator and water pump, from undue stress and premature failure. A well-designed chain tensioner can also help boost engine performance and efficiency. Continue reading

If/Else Parameter Expressions

We occasionally get questions about writing if/else parameter expressions. For instance, users may be setting up a parametric model where the heat turns on only under certain conditions or perhaps an input or output is best expressed as a step function.

Yes, you can do this with expressions. Lets look at some basic examples. Continue reading

Readers Choice for Top 5 ANSYS Advantage Articles

I enjoy working on every article I coordinate for ANSYS Advantage magazine. I always learn something new while assisting ANSYS customers and staff tell their stories of excellence in engineering simulation. I have no favorites as I appreciate all of the articles. But, I decided to let our readers choose their top five, based on the power of downloading. The following are the most-read articles from the four issues (three regular issues and one special issue for oil and gas) of ANSYS Advantage published last year. All these stories have one thing in common: They feature robust and reliable design practices. Drumroll please …

ANSYS Advantage for Simulation Driven Product Development

Have you picked up a copy of ANSYS Advantage Magazine lately? You can see the latest issue online and even subscribe to receive notifications of new editions. Every quarter, ANSYS Advantage Magazine includes stories about how engineers are using simulation tools to develop better products. A key trend is that more and more of us are using advanced design exploration and optimization tools to drive their simulation towards the most optimum and robust designs.

DXWordsFor Q3 of 2013, ANSYS Advantage dedicated the entire edition to shine a spotlight on robust design and optimization. You can read about how oil and gas companies like Technip are using ANSYS DesignXplorer to ensure against undersea oil leaks. There is also an article about how the electronics industry is using ANSYS DesignXplorer to help explore their design space and improve product performance. There is even a tech tip article (that I wrote ;^) to explain how to use the relatively new HPC Parametric Pack licensing to run simultaneous design points more cost-effectively. Continue reading

Are You Moving Forward with Robust Design Practices?

Safety mirror in an automobileWe just published a new ANSYS Advantage magazine issue that deals with product integrity and robust design practices, and my work brought to mind a story I want to share with you. I had a first-generation LCD display in the rear-view mirror of my last car. This device was very handy to access GPS as the display showed in the mirror and didn’t require any alterations to my built-in audio system nor an unattractive GPS mount on my windshield. However, on this particular day, the display seemed to fail when I was in the middle of nowhere trying to find my way.

It is likely this malfunction occurred for a number of reasons. The combination of my heat-absorbing black car, driving in the south of Italy where the temperatures can reach up to 60° C, and the time it takes to cool the interior after switching on my air-conditioning, might not have been the parameters the equipment designer tested prior to production. Although I liked the functionality of the GPS, this product didn’t work in the real environment in which it needed to perform.

Voyager: The Model of Robust Design Turns 35

I’m a big fan of birthdays. For the month leading up to mine, everyone – I mean everyone – around me knows it’s coming. But since we have a few months to The Model of Robust Engineeringprepare ourselves, I want to focus on a different birthday in this post. Voyager, the long-forgotten spacecraft and media darling of the 1970s, turned 35 this week.

Voyager captivated the imagination of the young and not-so-young as it beamed backed stunning pictures of Jupiter and Saturn (and the equally captivating images of Uranus and Neptune from its twin Voyager 2). Voyager is now, quite literally, where no one has gone before – near the edge of the solar system.

Automotive Simulation World Congress: Ladies and Gentleman Start Your Engines!

2012 Automotive World Congress

On October 30 – 31,  ANSYS will be hosting the Automotive Simulation World Congress 2012 ASWC Venue(ASWC) in Detroit, Michigan. This international event is being held at the Detroit Marriott at the Renaissance Center and is solely focused on the automotive industry, including vehicles for road, rail, racetrack and off-highway and provides a forum for sharing and debating new practices, issues and industry trends. You’ll learning about the latest developments in engineering simulation applicable to the automotive industry, and networking with peers. Continue reading

Trends in (Computer-Aided) Engineering Driving HPC Innovation

Last Friday, I gave a keynote talk at HP-CAST18 in Hamburg, Germany, about the trends in engineering that are driving HPC innovation. It was my first time joining HP’s worldwide HPC User Group Conference, and I was particularly impressed by HP’s detailed roadmap for new platforms, storage systems and low-energy computing, as well as their progress towards exascale computing.

I felt honored to be invited to speak in front of HP executives, HP technical staff, industry analysts, HP customers and partners. It’s a sign that HP seriously takes into account input from ISVs (independent software vendors, like ANSYS). Basically, my presentation identified some major challenges and trends in (computer-aided) engineering that are driving the demand for more HPC software innovations. Continue reading

Virtually Testing Robust Systems: Utopia or Reality?

It sounds fascinating, if not futuristic, that you might be able to virtually test a new product in any stage of design, under any extreme condition that it might experience during its lifecycle. If this were the case, product failures would soon be a thing of the past. But, on a serious note, can we really virtually fly an airplane, drive a virtual car or run a nuclear facility remotely to ensure performance under any circumstances?

Recently, I listened to an amazing presentation given by a German automotive supplier, discussing megatrends in the auto industry. The speaker concluded by describing a 2020 vision of simulating the complete car with modular simulation tools. Their 2020 target was a digital prototype for the entire car. Utopia or vision?
