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

PowerCone™ Wind Turbine Development Accelerated with Simulation

Artist rendering of the PowerCone

The journey of BiomeRenewables’ PowerConeTM wind turbine started with witnessing a falling maple seed. I was sitting on my deck when I was struck by how slowly the seed was able to fall. As it turns out, maple seeds — for their size — exhibit maximum aerodynamic efficiency; they are able to hit what is known as the Betz Limit — 59.3 percent aerodynamic efficiency. Careful analysis revealed that there is something about the seed’s shape and the way it interacts with the air that allows it to achieve such high efficiency numbers — namely, that it interacts with the oncoming flow at an angle greater than 90 degrees. This is not the case with modern wind turbines, which interact with the wind at perpendicular angles of 90 degrees. Continue reading

The Next Big Thing in Engineering Simulation

All great discoveries and inventions begin with a vision. A vision to make a better product, solve a unique problem or make life easier in some capacity. For centuries scientists and engineers have made tremendous progress in discovering scientific phenomena, or in solving technological challenges. I could write extensively about many of those inventions and discoveries, but there is one I would like to highlight.

In 1928, a Scottish biologist named Alexander Fleming returned to his lab from vacation. As he was sorting through some petri dishes he noticed something unusual. One particular dish had several colonies of bacteria and a cluster of mold. However, there was no bacteria growth near the cluster of mold. Although he did not realize the magnitude of his observation at that moment, he would later be credited with discovering the first lifesaving antibiotic, which he called penicillin. Continue reading

CFD Simulation of HVAC Systems on Trains Makes Rail Travel More Comfortable

Every time I travel in Europe, I enjoy riding the fast, comfortable trains. Riding from city center to city center without long security lines and tight uncomfortable airplane seats (worse for me because I’m tall!) can even make travel pleasant. But, I’ve always taken that comfort for granted. Were trains not always that way? Then, I found out about the challenges that Siemens engineers face as they design passenger coaches. Now I have huge respect for those engineers. Read on to find out how CFD is making their lives easier while giving me the comfort I love.

How ANSYS Simulation is Helping Virginia Tech Team to Optimize Hyperloop Pod

After placing fourth at the SpaceX Hyperloop Design Weekend in January 2016, as well as the first ever Hyperloop Pod competition in Los Angeles, California, Hyperloop at Virginia Tech is working tirelessly toward improving every aspect of their pod. The Virginia Tech design team comprises over 60 people, branching out to all majors within the university, from business to aerospace engineering. We currently follow a tick-tock engineering cycle, innovating for one competition, then optimizing for the next using ANSYS Simulation. Continue reading

ANSYS Advantage: Simulate Early for Successful Products

ANSYS Advantage Issue 2 2017The vast majority of engineering decisions are made without the insights that engineering simulation could provide into the impact of those decisions. It is estimated that 80 percent of the total product development costs are locked in by choices made early in the design process — and subsequent analysis and optimization now has to live within the implied constraints or face very costly and time-consuming design changes.

With increasingly complex products taking advantage of advanced materials, additive manufacturing and IoT, this issue will grow exponentially as many more permutations and design options must be evaluated for any given product. The only way to harness the potential of these mega trends, and tame the inherent complexity, is to bring simulation upfront in the product development process. To design the products of tomorrow, leading companies are doing exactly that.
