Design Automation Conference and LiveWorx – Big on IoT and Machine Learning

In June, I attended the Design Automation Conference in Austin, TX and LiveWorx in Boston, MA.  I would like to share some key observations from both events.

  1. The Internet of Things is going to be big; very big!
  2. Success requires partnerships.
  3. IoT is about monetizing data.
  4. Engineering simulation is essential.

The Internet of Things is going to be big!

At the just concluded Design Automation Conference in Austin, speaker after speaker stressed this.

Silicon Labs CEO, Tyson Tuttle, noted that there will be 70 billion Internet connected devices by 2025 with accompanying semiconductors to power them. He repeated McKinsey’s forecast the the Internet of Things will drive between $4 -11 trillion in global economic impact by 2025. Continue reading

In Search of a Better Design with Topology Optimization

When reducing the mass of your models, are you also optimizing for other important design elements such as thermal performance, fabrication constraints or if the casting needs to be water-tight?

Thermal problems are very common in engineering design such as automotive powertrain, electronic cooling system, etc. Topology optimization can also be applied for thermal analysis to improve the cooling performance or for coupled thermal-mechanical analysis to improve the thermal and structural performance simultaneously.

Onewheel: A Turbocharged Skateboard Powered by ANSYS

Most people occasionally have dreams of flying — without the aid of an airplane or other mechanical device — just soaring through the air on their own power. The thrill ends with dream, unfortunately. Closer down to earth, many of us enjoy the feeling of gliding effortlessly across the snow on skis or a snowboard, over the ice on skates, or on a surfboard cutting through the water. There is something about the effortless gliding sensation that can’t be approached by the more mundane act of walking — though walking has its pleasures too.

UC Motorsports Wins the Dynamic Event with ANSYS CFD

Each year the University of Canterbury Motorsport (UCM) team in New Zealand pushes the boundaries of what can be achieved in racing; in 2016 they overcame their greatest challenge to date. After three years (2013-2015) of competing in the Australasian Formula SAE competition with an internal combustion engine vehicle , the team decided in 2016 to design and build New Zealand’s very first four-wheel drive (4WD) electric vehicle for the competition. The results were remarkable: UCM made history by becoming the first team with an electric vehicle to win a dynamic event at the Australasian Formula SAE competition.

Celebrating International Women in Engineering Day – Friday, June 23rd

Dr Shini Somara Women in EngineeringToday we celebrate International Women in Engineering Day. Recently, I had the opportunity to meet with Dr. Shini Somara over coffee one afternoon. Shini is a broadcasting science and technology journalist who reports engineering and innovation on television and online, both in the UK and USA for networks such as the BBC and PBS. She began her career as a fluid dynamicist, having studied mechanical engineering at Brunel University and has always been passionate about making the invisible, visible!  An interest that began with Bernoulli’s equation and has continued through her communication of science.  

When we met, we started to share some common views about how to encourage more engineers into this field. Dr Somara is well placed to discuss this with her tireless work advocating STEM education, including providing free online education on physics, through a 48-episode series called Crash Course: Physics Continue reading

Interactive Script-defined Tools Change the Game in Modeling

If you turn on the TV or browse the internet these days, automation is a familiar topic. From smart homes to learning thermostats, the drive to save time and effort by automating repeated tasks is everywhere. We use words like ‘smart’ to indicate that our devices are no longer one-size-fits-all but instead adapt and can be programmed to better suit our needs and behaviors. So, too, should be the case with our engineering software! That is why we have spent over a year to add scripting, a broadly applicable interface for automation and customization of modeling, to the ANSYS SpaceClaim geometry modeling environment.

In a previous blog post, we introduced SpaceClaim scripting and how it can automate repetitive or tedious tasks. With ANSYS 18.1, we’ve taken it a step further and made it easier to share and use SpaceClaim scripts outside of the editing environment. By publishing scripts to dedicated buttons in the user interface or calling them from within a Workbench script, you can now use the power of scripting in more places than ever before. Furthermore, we have extended the interaction with scripts to allow for user input of selections and values during execution. Let’s take a closer look at these improvements. Continue reading

Antenna Industry is Being Revolutionized Through the Simulation of Metal 3-D Printed Antennas

Recent advances in 3-D printing with metal have advanced to the point where antennas and RF components can be consistently fabricated with excellent performance in the millimeter wave frequencies. Optisys is a startup based in Utah that is focused on using the most advanced simulation tools to design antennas and radio-frequency (RF) components that could not have been fabricated a few years ago. The use of 3-D printing an antenna creates orders of magnitude reduction in size, weight, and lead time. These savings are enabled through a key partnership with the ANSYS Startup Program.

Women in Tech and the NAFEMS World Congress

women in tech engineering 3D

About 6 weeks ago, I attended the NAFEMS Multiphysics and Multiscale conference in Columbus, Ohio, USA. I have witnessed the benefits women in tech bring to their companies and themselves and make a habit of counting how many women are at these events. I am excited when the number of women exceeds 10% of the attendees. This event did not quite meet that benchmark. Most conferences I attend in the simulation space do not. As a woman in tech with a keen interest in increasing the number of women in engineering and technology as well as promoting and supporting those already there, I find this disheartening.

Efficiently Modeling Turbulent Combustion with Realistic Chemistry Using a Flamelet-Generated Manifold

The main challenge of turbulent combustion simulation is to resolve turbulent mixing together with the chemistry of combustion involving hundreds of molecular species, in a solution time that is compatible with engineering design. Steady diffusion flamelet-based turbulent combustion models have been used for nearly three decades. The computational efficiency of flamelet-based models has been the key to their widespread success in industrial applications. However, increasingly stringent emission requirements continuously push designers to incorporate more finite-rate chemistry effects for the engine simulations in a more comprehensive manner.

True-Load Software and ANSYS Workbench Solve Difficult Strain Challenges

As the founder and president of Wolf Star Technologies and the creator of True-Load software, which calculates the loads from measured strain occurring in moving vehicles, I would like to tell you a little about the struggles and triumphs I encountered (and overcame) in my engineering career and how this led to the creation of True-Load. This has culminated in the successful integration of True-Load into the ANSYS Workbench platform, so more engineers than ever will have access to my software and be able to integrate it with their ANSYS simulations.
