Multiphysics Simulation Reduces Automotive Noise

You are having a discussion with your passenger while driving and you raise your voice to be heard as the car goes faster. Or, you pull onto the on-ramp of the highway and instinctively turn up the volume on the car stereo (that is, if you don’t have a car stereo that’s programmed to increase the volume as your speed increases to overcome the ambient noise). So, you may not be surprised to learn that J.D. Power lists high levels of automotive noise as one of the most commonly reported problems. To tackle this challenge and design quieter rides, engineers at Corning use ANSYS multiphysics simulation software.

Digital Twins: Realizing the Predictive Maintenance Vision

One of the newest and most exciting frontiers in simulation is the concept of digital twins. According to recently released survey results reported by Gartner, 48 percent of companies already realizing the benefits of the internet of things (IoT) are using or plan to use digital twins by the end of this year. And, at least 50 percent of manufacturing companies with annual revenues of more than $5 billion plan to start at least one digital twin initiative by 2020.

But first, what is a digital twin? The term is wildly used across industries with various meanings. Here’s how I define a digital twin: It is a simulated, virtual model of an actual working product in the field, informed by sensors mounted on the physical product that gather and send back real-time, real-world operating data. By studying the digital twin under actual working conditions, companies, for the first time, can analyze the product in action, over time, in its actual operating environment. This feedback enables the product development team to close the loop on its initial simulations by revealing strengths and weaknesses of the design in the field. Engineers can make more informed choices for future designs and improve the accuracy of their simulations.

Even more important, digital twins enable true predictive maintenance for the first time. Instead of overservicing or overmaintaining products to avoid costly downtime, repairs or replacement, companies can act “just in time” to address any product performance issues predicted by the digital twin. They can accurately visualize exactly when and where maintenance is needed, instead of making blind guesses and safe bets. Costly unplanned downtime is replaced by less expensive maintenance during scheduled shutdowns. Continue reading

ANSYS Discovery Release Powers Up 3D Design

On the heels of February’s exciting product launch, we announce the first point release for the ANSYS Discovery family of products. Our development team has been hard at work to incorporate customer requests, enhancements and workflow improvements to make 3D modeling and simulation easier for all designers. As much as I’d love to share all that’s new for you in Discovery 19.1, for now, I’ll focus on a few.

ANSYS Discovery Live — Fluids

In Discovery Live 19.1, we’ve expanded the usefulness of specific fluids displays. Users will realize more accurate and robust results that deliver valuable feedback in a shorter amount of time. For example, when measuring pressure or velocity, users will see transient solutions converge (settle down) significantly faster than before. Also, when visualizing velocity using surfaces, isosurface or composite smoke-like view, users will also gain greater confidence in the accuracy and reliability of their simulation results.

 

The transient fluid displays in Discovery Live 19.1 are now faster and more accurate.

 

 

A new vector display for fluids combines the detail of flow lines with the animation of particles. Non-time-dependent arrows, which show results faster, give insight into the direction and velocity of flow, while greatly improving the visibility (versus traditional flow lines).

 

The Discovery Live 19.1 vector display increases visibility while displaying direction and velocity information.

Leading by Example: Tech Parents on Raising Daughters

As we prepare to celebrate Mother’s Day in the United States, we wanted to share the perspectives of our ANSYS team members on what parenting in the tech world means to them.

Preeti Gupta, product director, semiconductors

Our children are growing up witnessing momentous world changes that are sure to propel society forward. As parents, we have the privilege and responsibility of helping shape the thoughts of our little girls and boys. A recent “Women in Technology” event, co-hosted by ANSYS, was an eye-opener for me on the importance of exposure for these very impressionable minds.

As with all mothers who are also pursuing a career, my day starts early and ends late, and every minute counts! Evening networking events are an inconvenience as they put a dent into an already packed schedule. They have to be really important for one to take precious time away from other commitments, like taking care of the needs of children who have been at school for over 10 hours or catching up on work or chores! Considering all of this, I am very glad that I not only attended this event, but also brought my daughter along.

The event itself was a high-impact panel discussion among women achievers in the field of technology on the following topics: personal branding, leadership, negotiation, networking and mentoring. It was a revelation that certain facets of my personality and challenges that I felt were unique to me are actually common behaviors exhibited by women in general. Nuggets and insights came out of the discussion that were of tremendous value to all. Half-way through the discussion, as I sat enraptured, my daughter asked me for my phone and I quietly handed it to her, fully expecting her to open up “Temple Run.” After all, how would an elementary student connect with this discussion and find it interesting?

To demonstrate the power of influence, these are the notes my 10-year-old took on my phone — completely on her own initiative with no encouragement from her mother:

  • Lead yourself with what you are good at.
  • Try to make yourself shine.
  • Always respect mentors.
  • Cannot “manage” army in war, “lead’ it.”
  • Figure how to problem-solve.
  • Make decisions.
  • Have communication, courage, consistency.
  • Be able to negotiate.
  • Understand your value and be passionate.
  • Do not take advantage of people.
  • Do not lose people’s trust.
  • Do not be too humble.
  • Do not be shy.
  • Add value to the next level.
  • Do not compromise passion and calling.

And, the morning conversation on the way to school the following day was on personal branding, networking and mentoring! As a parent of two daughters, my only regret was that I hadn’t worked out the schedules so that my older daughter, a sophomore in high school, could also attend.

Some events become defining moments in our lives and this was one. Take the time to proactively seek such opportunities. I know I will. It is more than worth it — for us as fathers and mothers, for our sons and daughters!

Dave Horn, digital marketing manager

A proud dad may exaggerate, but the grades don’t lie. My daughter, a fifth-grader, has received more A’s in math than I did throughout the entirety of my scholastic career.  She loves the detective work and the “aha” moments when a previously challenging or “blurry” problem suddenly presents a clear solution.

This mindset has led her to also love science and technology. While stuffed unicorns and llamas line the shelves of her bedroom,  down in the basement there are model rockets ready for spring and, in the family room, there is a laptop where Scratch and now Python™ are used to (mostly) silly effect.

So, what does a dad — the youngest of three brothers, who grew up in a small town where men did the work and women raised the kids — do when his daughter wants to spend the afternoon building rockets?

He embraces it all.

Thankfully, it seems that the “this is a girl thing and that is a guy thing” way of thinking is dying a long-overdue death.  To the people like Stephanie Kwolek and Margaret Hamilton who helped put the nails in the coffin of this way of thinking, thank you.  The loss of potential in the sciences and arts from people who gave up what they truly had a passion for because it was deemed unseemly for their gender is inestimable and infuriating.

So, what does a dad — the youngest of three brothers, who grew up in a small town where men did the work and women raised the kids — do when his daughter wants to spend the afternoon building rockets?

He thanks everyone who helped break down the barriers and heads to the basement to help build a rocket that will go quicker and higher than the last one.

Susan Coleman, marketing manager, academic and startup programs

This Mother’s Day is extra special for me because it is my first time celebrating as a mother. Growing up, both of my parents worked, and I had very involved grandparents who filled our time away from home with amazing memories. Having a working mother inspired me to work toward a fulfilling career but, in retrospect, her example gave me even more than a strong work ethic. She taught me to ensure that people can always count on you, and that your name and your word are all you have in life, so don’t put yours on something that you haven’t given your all to. She also taught me that you may not be able to control if you are the smartest person in the room, but you have complete control over being the hardest working person in the room.

These lessons influenced my decisions throughout college and my career. Now that I have a daughter of my own, I am passionate about not just teaching her these lessons, but always leading by example.

My career experience started in marketing and media, but I didn’t let that hold me back from leveraging my skills at an engineering software company. Children (boys and girls) should grow up knowing they can choose any career they want in life.  For instance, gender should never hold a boy back from choosing a career in nursing, or a girl from an engineering degree. We should seek a professional path that allows us to balance our strengths with doing something we love. Our companies and industries will be strengthened from this diversity, and we will be happier, both as employees and as human beings.

 

Additive Manufacturing Advances Cooling Limits

All businesses strive to increase efficiency and lower costs. If your business fails to innovate, your products will be surpassed by others that do. Imagine that your latest product design achieves higher efficiency in a smaller package but, when you bring it to your tooling supplier, you learn that it will take considerable cost and time to validate the tooling you need. What will you do? The tooling manufacturer has limitations in its manufacturing processes that limit your options to get a better product to market faster. If only it had access to the leading simulation software and the latest advances in additive manufacturing technology, the supplier would be able to solve this problem instead of forcing you to take measures into your own hands.

Simulation is UniNa Corse Team’s Formula for Success

As newcomers to the Formula SAE competition, we, the student members of the UniNa Corse team, debuted our first car at FSAE Italy 2017, which was held at Varano de’ Melegari. We also finished first in the sponsored Virtual Formula 2017 competition. Having achieved this important goal, our main objective for 2018 is to optimize the 2017 car without introducing any additional problems, as we prepare for FSAE Italy 2018 and FSG at Hockenheim.

UniNa Corse Team Picture

The focus of our design was on the car’s aerodynamics profile. We used ANSYS computational fluid dynamics (CFD) simulation software to analyze the 2D performance of various airfoil designs to achieve the best performance in terms of downforce while minimizing drag forces. After creating a mapped mesh using the ANSYS meshing software, we ran the flow simulations and quickly captured all the relevant flow field characteristics, thanks to the software’s fast convergence speed.

Sensing the Future of Autonomous Vehicles: ANSYS Acquires OPTIS

Barely a day goes by without some type of autonomous vehicle — self-driving car, drone or mobile robot — making the news. Today, we’d like to add some autonomous-related news of our own. It is with great excitement that we officially welcome OPTIS, the leader in optical simulation, to the ANSYS engineering software family.

Why is this big news for our customers? Well, it would be impossible for a vehicle to drive, fly or maneuver independently without the sensors that help it perceive and safely navigate the surrounding world. These sensors come in several forms, the most prominent being radar, lidar and video cameras. Each has performance strengths and weaknesses that are influenced by variables such as weather and the surface properties of objects. By combining the input from a variety of sensor types, the software brain of the vehicle can construct a complete picture of its environment, in a wide range of conditions.

The decisions made based on the sensors’ feedback can mean the difference between life and death. Safety is paramount. And to ensure prototype vehicles are real-world ready, these sensors must be designed and tested using the highest fidelity, most accurate simulation tools available. Continue reading

Electric Transformer Design with ANSYS Discovery AIM

Transformers are used extensively in electronics products to modify voltage before electrical energy can be transmitted. Image of electric transformer.Alternating current in one coil produces a varying magnetic field that induces electromotive force, allowing power to be transferred from one coil to another through a magnetic field without metallic connection. Designing these electronics systems is an art of maximizing or minimizing induction depending on the requirements of the circuit. Computational electromagnetics can confirm good coil proximity and sizing in systems where maximal inductance is required, such as in the case of a shared iron core within an electric transformer. Alternatively, it is desirable to identify stray flux leakage when inductance is unwanted, such as between a circuit coil and metal framing used in a housing. Current is needed to drive through the coil, but you also don’t want the electromagnetic effects to be inducted within the framing and, as a result, generate undesirable heat or reduce the efficiency of the system.
