Simulation Innovations: From Systems Simulation to Autonomous Vehicles to Digital Twins

The role of 3-D physics, systems simulation and embedded software is expanding rapidly into new industries and disciplines. A few years ago, 3-D physics simulation was limited to specific departments within organizations, and often these departments did not coordinate with each other on product development activities. Fast forward to today, and much has changed and must continue to evolve in order for companies to remain competitive in the changing landscape of product development. Integrated 3-D physics, systems simulation and embedded software tools are of the utmost importance — especially when tackling the challenges of quickly and accurately developing the technology driving digital twins and autonomous vehicles.

Join us in Paris for our Innovations Conference on December 5-6 and learn how our customers are using simulation to bring their products to market faster.

Interference-Free Design of Electronic Devices

Have you ever relaxed on the patio on a beautiful autumn day while using your mobile phone to talk to a friend, stream some relaxing music over the phone’s WiFi connection and maybe use the built-in GPS location capability while you map out your next family road trip, all at the same time?

Just think about how amazing it is that you can do all of that — and more — with a device that you hold in the palm of your hand. Your mobile phone has more computing power than the computers that put man on the moon, and more wireless connectivity than we would have thought possible less than a generation ago!

Free Performance Benchmark Program

Whenever I speak to our customers who want to run our software on something more powerful than their desktop computers, I hear the need for quantitative proof of HPC benchmark tests. If you have the same need, you can now get that proof, and it won’t cost you a thing.

We’ve established a Free Performance Benchmark program. Instead of demonstrating evidence of the benefits of HPC on standard benchmark models, we want to show you the time savings that HPC can make possible for your very own model. Continue reading

European Microwave Week on the Horizon

European Microwave Week 2017 is almost upon us. The 6-day event provides access to the very latest products, research and initiatives in the microwave sector. It also offers attendees the opportunity for face-to-face interaction with those driving the future of microwave technology. Our ANSYS experts have been attending this conference for a number of years, and I’m proud to say we’ll be there again this year.

From October 10-12, you can stop by our Stand 103 to get the most up-to-date information on our solutions for RF, microwave and communications systems. I’m personally honored to be presenting two papers this year that I hope you’ll attend. Continue reading

The EnSight CFD Simulation Post-Processing Story: Like a Multi-Stage Rocket

EnSight, the leading post-processor for Computational Fluid Dynamics (CFD) data is now part of ANSYS. In the two decades since its launch, EnSight has taken off like a multistage rocket. Here is the story.

I grew up in that magical era when NASA used multi-stage rockets to carry Apollo astronauts to the moon and back. As a toddler I learned to count backwards from 10, 9, 8, 7, 6 … because that’s what I heard Mission Control say. I dreamt of being an astronaut, studied aerospace engineering and started my career at NASA’s Johnson Space Center in Houston, Texas. I met my lovely wife there, blocks from the NASA gates. Her parents still live next door to Buzz Aldrin’s Apollo era house. I used to store my lunch in the Mission Control fridge while working on my space shuttle aerodynamic simulations in the support room next door. So maybe it’s natural for me to think in rocket terms.

AESE: Simulation for a More Connected World

Today, after a video call with my kids at home, I feel more relaxed. Usually on long distance business travel, we are always concerned about the family at home. A few years ago long distance voice calls were not only costly but also of poor voice quality. Now, equipped with mobile phones, we can make high-quality audio/video calls and exchange text messages with people around the globe, at little or no cost.

It’s amazing to see the way communication technology has grown over the years. Technologies that seemed like fiction a few years ago, are now becoming reality. These include virtual reality, 3-D hologram and printing, language translation, and mobile streaming audio and video.  Continue reading

Calibration of a Numerical Simulation with Experimental Results Critical for Reliable Predictions

Every numerical method relies on the accurate choice of models, solver settings, and material parameters in order to be able to mimic real-world behavior. This also applies to Discrete Elements Method (DEM) simulations. You could use standard material properties, but adjusting those material interaction parameters using automated calibration methods is a key step for accurate simulations.

You could use standard material properties, but if you want to simulate reality, it is important to understand that the materials actually vary from site to site. Adjusting those material interaction parameters using automated calibration methods is a key step for accurate simulations. Even with basic materials, friction and restitution coefficients between particles and particles and boundaries have to be adjusted in order to accurately predict the bulk flow behavior. When extra forces come into play, such as adhesion forces, those additional parameters also need to be selected and properly specified. Continue reading

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

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.
