Simulation Tools for Electromagnetic Interference

This post originally appeared on the Dassault Systèmes blog.

The world of electromagnetic devices is rapidly expanding, to include everything from smart devices in our homes to medical devices in and around our bodies. This technology is opening up many doors, allowing us to live more enriching and even healthier lives, but, like all good things, the technology comes with potential complications. When discussing electromagnetics, the term EMC/EMI often comes up. EMC stands for electromagnetic compatibility, which involves the unintentional generation and reception of electromagnetic energy. This energy can cause electromagnetic interference (EMI) and even damage in devices that unwittingly receive it.

EMC is the ability of an electrical system to properly function in its intended environment without influencing other devices, also known as giving off emissions, or being influenced by surrounding devices (known as immunity or susceptibility.) Emissions and Immunity is a well-regulated area, and compliance with these regulations is critical for all electromagnetic products.

In the past, EMC engineering was associated primarily with measurements, and could only be applied late in the design stage, as a physical prototype was required. If problems appeared, a great deal of effort was required in troubleshooting and applying countermeasures in order to pass rigorous testing requirements. Frequently, only the symptoms were addressed, with the underlying problem remaining undetected. This approach is cost-intensive and can potentially delay the time to market of the device significantly.

Simulation is a valuable tool in mitigating EMC issues, and can be used both during the design phase and during troubleshooting. Using it as early as possible in the design phase, however, has the potential to mitigate the need for later troubleshooting. Simulation can be used without a physical prototype, and can answer important fundamental questions such as whether to use a shielded or unshielded cable, for example. Beyond that, simulation gives access to information that is far beyond what measurement can offer, peering into the depth of products and evaluating the effects of even the tiniest of details.

CST Studio Suite contains a circuit simulator, which can be coupled with the full wave 3D electromagnetic simulation, offering unique possibilities for the user such as the ability to obtain field results that consider an attached circuit. It also allows the user to calculate field distribution at the speed of a circuit simulation as long as the geometry of the device is not changed, thereby greatly reducing the time and effort needed to evaluate a multitude of different circuit configurations and their effect on the system efficacy.

A tool called BOARDCHECK can be used very early in the design process to visually highlight potential problems and provide a list of all violations on a printed circuit board level. It is fast and easy to use, and is the first step in the process, after which 3D simulation can be run. Overall, CST Studio Suite provides a full spectrum of solutions for EMC/EMI simulation in a single, unified simulation environment. It offers support and openness to third party models and file types, such as CAD, PCB layouts, spice, IBIS, and more. It can be easily integrated into existing toolchains and offers a variety of solvers for different applications and use cases.

Sustainability Forum: How Science & Tech Will Influence Our Health, Our Lives, and Our Work

You may be on your way to digitally transforming your company, looking for help to collaborate, or maybe just dipping your toe in the digital waters. And you may be wondering what the future holds…this report will shed some light on key real-world issues for you to consider in your transformation.

The Sustainability Revolution

This report is a synopsis of a two-day forum in Boston called Science in The Age of Experience, hosted by Dassault Systèmes who is using software to help companies design a more sustainable future. There were over 300 scientists, business executives, engineers, professors, and leaders in various industries using science and technology to imagine a new digital world that directly influences how we live, our health, and how we work.

Dassault Systemes
Bernard Charlès, VP and CEO Dassault Systèmes

Bernard Charlès, VP and CEO at Dassault, opened the forum. In a nutshell, the Digital World isn’t just about creating better designs, optimizing manufacturing, and getting to market faster. It gives companies the chance to examine their business models and the impact their products have on society.

Digitalization can help companies transform into a more sustainable organization and develop products that are more beneficial to people and the environment. Charlès advised to “look at the world with fresh eyes”…and use the power of imagination guided by science to innovate and solve the world’s biggest problems together.                             

More than 15 speakers, from scientists and engineers to industry leaders, took the stage. They discussed how the virtual world is disrupting innovation while developing real-world sustainable solutions that have never been done before.  

How Do You Study, Test, and Implement Sustainable Innovation?

There is a “hunger for tools to solve world problems.” Throughout the forum, these leaders discussed three key ways to study, test, and implement sustainable innovation to move ahead.

#1 Simulation-Driven Design

Being able to use a virtual 3D model to explore the behavior, performance, and interactions of a product or a system from the beginning and track it to the end-of-life is powerful.

“Science is at the core of what we do. Simulations give you the visual cues, the feedback you need, to know what to focus on.”- Raja Sengupta, Global Technology Specialist, Aerodynamics at Volvo Trucks

  • Simulation-driven design allows you to make mistakes and capture risk early, before products are physically produced.
  • It saves resources and materials to eliminate waste.
  • Scientists and engineers can virtually investigate the relationships between a concept and its environment to understand how all components work together.
  • Virtual models using tools like VR and AR can be used as interactive teaching and learning tools.
  • You can explore infinite possibilities virtually at a rate that can drastically speed up solving big challenges.

 #2 Data

Dr. Lisa Randall, Physics Professor at Harvard University, explained:

By doing simulations and having data, we can really do things at a level where we can probe the fundamental interactions of things we can’t see, like Dark Matter.

The ability to use data and tools like analytics, artificial intelligence (AI), and machine learning (ML) helps to collect, analyze, and use the insights uncovered for process improvements, new sustainable techniques, and increasing yield and profitability. 

Dassault’s Dr. Anne Goupil says, “We need to devise creative ways to sift through mountains of data that is produced during treatment.” She described a case study where researchers used the collaborative and analytics portions of the 3DEXPERIENCE to develop treatments for health issues.

#3 Collaboration

You can’t solve challenges like sustainability, alone. High-end innovation adds another layer of risk.

These leaders talked about putting competition aside and collaborate with the entire ecosystem in your industry and beyond. Companies who have a common goal of safety and sustainability can combine experiences and resources. Proven technologies and transformations in one industry can be applied to another.

The Living Heart Project, originated by Dassault on the 3DEXPERIENCE platform, was live at the forum. This project has brought together over 125 organizations since 2014, from leading cardiovascular researchers, medical device developers, regulatory agencies, educators, practicing clinicians, to the FDA.

They are on a shared mission to create virtual designs and testing of devices, digital therapies, and drug treatments for heart disease, pacemaker leads, stents, valves, and more. This will enable patients to access safe, effective, and new treatments much faster.

How is Science Driving Sustainability?

Bakul Patel, Director of Digital Health for the FDA

The forum was focused on sustainability using science to reinvent three major areas that affect our lives: better living, a sustainable planet, and product innovation. These are a few of the takeaways from the forum.

#1: Science in Life for Better Living

Health was a key topic. Peter Bergethon, VP of Digital and Quantitative Medicine at Biogen, shared, People like the idea of living longer and so personalization matters.”

Better Drug Treatments

 Dr. Ameet Nathwani, CDO & CMO of Sanofi, explains, “Drugs for many diseases are only part of the solution. If you’re lucky, you’ll get a 50-70% response. But we do know that technologies can amplify the value of drugs and the outcome.”

Using Dassault technology, especially simulation, they can determine when to expose the drug at the right time, in the right place, for that particular patient.   

New Digital Services Speed Up the Process

Services like smart remote diagnostics and Telehealth can assist healthcare professionals & patients with better solutions.

Pierre-Yves Frouin, CEO Bioserenity, explains, “We focus on electro-physiology, and we see that it speeds up processes significantly. We can help the right patient, receive the right treatment, much faster.”

Glen de Vries, President and Co-founder of Medidata Solutions

Glen de Vries, President and Co-founder of Medidata Solutions and a leader in digital transformation for clinical development, commercial, and real-world data, talked about advancements in clinical trials. Clinical trials not only take years, but also cost billions of dollars. Simulations can assist in finding the right treatment protocol for the outcome and a patient can receive the treatments in weeks instead of years.

In the end, he explained, “We are taking diseases that were chronic and curing them, and we’re taking life-threatening diseases and rendering them chronic.”

A New Era of Bionics

Dr. Hugh Herr, Professor at MIT and head of the Biomechatronics research group, Co-director of the MIT Center for Extreme Bionics, and known as the leader of the bionic age, gave an amazing talk.

Dr. Hugh Herr, Professor and Co-director of the MIT Center for Extreme Bionics

Dr. Herr shared, “My legs were amputated in 1992 and my doctor told me I couldn’t climb or bicycle ever again. He was dead wrong… each of my legs has three computers the size of your thumbnail.”

He explained that the common goal is to eradicate disabilities and drastically reduce human pain and suffering.

At MIT, they are developing bionic prosthetics to help amputees and other patients run, walk, and hop; procedures where nerves activated by light could potentially restore mobility in paralysis patients; exoskeletons to improve the ability of people to walk, run, and lift; and in the future, extreme athletics where they develop bionic shoes to jump higher and run faster.

As Dr. Herr explains, “Tech is no longer lifeless tools but actually becomes part of the person”.

#2 Science in Nature for a Sustainable Planet  

Climate change is causing widespread destruction around the world. How can we make changes?

Move to Sustainable Manufacturing

Jennifer Wilcox, Professor of Chemical Engineering Worcester Polytechnic Institute

Marcel Wubbolts, Chief Technology Officer at Corbion says, “We are really heating up the planet in ways that are no longer sustainable. We have to move towards sustainable manufacturing.”

 Excess carbon is a big contributor.

Jennifer Wilcox, Professor of Chemical Engineering at Worcester Polytechnic Institute, explains, “We can’t just decrease CO2 from the air. We need to remove it.”  Wilcox says that carbon dioxide removal technology is available using a chemically manufactured approach and compares it to a synthetic forest. But more investments in R&D are needed.

She continues, “It’s not just about removing the carbon dioxide… It’s about certain sectors, such as transportation and cement making, that chemically produce carbon dioxide, and that’s a very difficult thing to avoid.”

Reduce Food Waste & Plastic Consumption

Marcel Wubbolts, CTO, at Corbion discussed providing safe and healthy food for a growing population, preventing food waste, safe solutions on renewable materials, efficient resource processes, and new biotech business platforms.

He talked about 10 breakthrough technologies to help feed the world, such as plant-based meat, compounds for keeping nitrogen in the soil, and algae-based fish feeds.  

#3 Science in Engineering for Product Innovation

Dr. Michio Kaku, Theoretical Physicist, Professor, and Author

Dr. Michio Kaku, Theoretical Physicist, Professor, and Author of Physics of The Future, The Future of the Mind, and The Future of Humanity discussed that data powers the Information Age. 

He predicts, Every industry will be digitalized, analyzed and visualized….”

He says that human and machine intelligence, AI and analytics, will need to make sense of this vast ocean of data via simulations.

Future of Simulation

Moving forward, all challenges that we are undergoing, like predicting hurricanes, developing a super battery, and even our memories will be simulated to identify risk, glean insights, and make better life decisions. 

Can We Simulate Life?

Dr. Michio Kaku, Theoretical Physicist, Professor, and Author

 Dr. Kaku describes, “We will have virtual reality in every aspect of life to visualize complex phenomenon.”  

He goes on to say, “Today, the Da Vinci robot allows us to do surgery via robots. In the future, perhaps even the human surgeon will be replaced, performing surgery first on virtual bodies, then on real bodies.”

However, he explains that even though machines, via AI and pattern recognition, can spot cancer in X-rays and MRI scans faster than doctors, they will not replace them. They will be an aid to them.

Dr. Kaku predicts that business meetings, conferences, tours, education, training, etc. will be done using virtual reality in all sectors.   

Consumer Products

Dr. Geneviève Berger, Chief Research Officer at Firmenich and recognized as one of the most powerful women in business by Fortune Magazine, examined consumer products says, All consumer products, one way or the other, if they want to be successful, need to have a positive impact on the quality of life.”

She discusses the overwhelming appetite for “natural” products. This leads to science and biotech innovations for products that are safe and even create habits and memories.

 Materials-Based Innovation

Neil Gershenfield, Director of Center for Bits and Atoms, MIT

If we want to drive sustainability, we must change the way we build. What happens with the materials we choose to implement? Is there a negative effect on the environment and on society?

Dr. Michael Doyle, Sr. Director Corporate Development for BIOVIA at Dassault Systèmes, discussed hybrid energy storage (batteries + hydrogen) and their challenges with things like state of charge, safety, aging, storage, sustainability, and recycling.

He states that we need to create materials for purpose, intentionally manufactured, and virtually optimized.

Neil Gershenfield, Director of Center for Bits and Atoms, MIT exclaims, “Evolution isn’t random. The heart of evolution is that it works over a carefully curated space. And that is the very insight of deep learning.”

Summary

Digital Transformation is a state of business.

Dr. Kaku predicts that, Every industry will be digitalized, analyzed and visualized…and without exception, we will be generating enormous amounts of data… Data will pretty soon replace crude oil and become more precious – just like crude oil, data will have to be filtered & refined.”

On your road to digitally transforming your company, remember to work on sustainability from product innovation, to the environment, to health and better living.

To help you move forward in your product development and manufacturing efforts, be sure to incorporate the big three tools: Simulation-driven Design and tools like AR and VR; Data using analytics, ML, and AI; and Collaboration.

Vibroacoustics

Optimizing NVH for EVs

This article first appeared in Automotive Engineering – October 2019.

Optimizing NVH for EVs

Unique acoustic and harmonic challenges require an integrated approach to simulation and analysis. An expert at Adaptive Corp. explains.

Despite global sales market share stuck at single-digit levels, electric vehicles (EVs) are steadily filling the development pipelines at major OEMs. And as engineers are acutely aware, EVs bring a paradigm shift in the noise, vibration and harshness (NVG) arena. Their harmonic spectra are dramatically different than those of even the smoothest, most refined combustion-engine vehicles and hybrids.

EVs are anything but silent, however. They’ve got their own acoustic challenges, experts assert. Traction motors can be relatively quiet (in terms of tonal harmonic noise) in the low and mid frequencies, but unmasked gear whine and various sounds in the propulsion system are far more noticeable and potentially annoying. There’s also the relative cacophony of the tire noise, HVAC fans and compressor cycling. Even electrical switching and the muffled gurgle of battery coolant can be heard in some EVs while at rest. 

While the industry is likely years away from customers complaining of EV cabin noise, leading practitioners in the NVH-reduction field are already working on up-front solutions. One of them is Adaptive Corp., a specialist in simulation, structural analysis and product lifecycle management for automotive, aerospace and other industries. Optimizing designs for improved performance (including NVH, weight, cost, durability) is Adaptive’s specialty, according to customers with whom Automotive Engineering spoke. The NVH science behind EVs and hybrids is increasingly a focus of Adaptive’s services, explained Wayne Tanner, the company’s chief operating officer. 

“It’s true that we have to ‘up our game’ with EVs,” Tanner told AE. “We’re hearing this from all our customers who are in the EV supply chain, such as those who make tires and suppliers of motors. We’re looking at components and subsystems that were never before considered to make the vehicle quieter.”

Easing the development crunch

The industry’s move to electric propulsion is driving new business across the engineering-solutions sector. Tanner, who is responsible for all his company’s activities related to simulation and analysis, notes that the industry trend is toward clean-sheet vehicle platforms dedicated to battery-electric propulsion. OEMs such as Tesla and Volkswagen – the latter’s dedicated and modular MEB platform to be shared by Ford on some models – are committed to this strategy that optimizes structural stiffness (with its related NVH benefits) and other attributes. 

“The time-to-market is increasingly short, which is why product-development teams need simulation to do their fast, quick iterations,” Tanner said, “and to make accurate predictions before they build prototypes and test vehicles.”

The aim is to avoid the dramatic and often eleventh-hour ‘band-aiding’ of vehicle structures. Such activities include costly material replacements and noise-path mitigation by adding heavy NVH countermeasures, in order to meet production deadlines. “That’s certainly something that we can help with if we’re brought into the development process sooner, farther upstream,” Tanner noted. Engineers sometimes don’t think of components and subsystems as a system until they’re actually put together, he observed. 

“Some customers, because they’re moving so fast, can’t find time to do a simulation upfront – then they discover the need for add-on countermeasures at a late hour,” he said.

Tanner has worked in simulation for over 20 years in various disciplines including design optimization, load development, weld fatigue and dynamics. He and other NVH experts assert that the sooner system-level and full-vehicle models can be developed in any vehicle program, the more effectively predictions can actually improve those designs to reduce NVH, rather than being band-aids in the end.

Inside the toolbox

For its simulation platform, Adaptive partners with Dassault Systèmes, whose 3DEXPERIENCE is rated by users as state of the art in comprehensive NVH simulation toolsets. “The advantage of (3DEXPERIENCE) is, it gives us a single data model that can contain CAD and simulation data,” Tanner said. “We connect that to systems engineering to drive requirements all the way from start to finish, to manage the workflow. Some of the tools we have at our disposal aren’t fully integrated into the platform, but we’re able to put everything together and manage that data. This allows our customers to access a single data source.”

Tanner offered a peek inside Adaptive’s extensive sim toolbox. On the aerodynamics /CFD side is PowerFLOW; on the acoustics side is another Dassault tool called Wave6 that’s used to project an acoustic signature. On the mechanical side, Adaptive engineers use Simpack, which helps them develop all the mechanical vibrations needed for a given analysis. There are also electromagnetic tools. 

“We connect all these tools into a single workflow – to drive mechanical and/or aerodynamic vibrations into the acoustic field, for example – on the 3DEXPERIENCE platform,” he said. Once an OEM is ready to begin road and/or dynamometer testing, they employ Adaptive to validate and correlate from the company’s virtual model into production models.

Another weapon in the arsenal is True-Load from Wolfstar Technologies. It leverages finite-element models to determine the optimum location for strain gauges on unmodified physical parts then generates load-scaling functions. The company claims typical strain correlation within 2% of measured values. Output feeds directly into True-QSE events, described by Tanner as “a powerful post-processing tool” that supports rapid virtual iteration.

“It allows us to take that test mule and put information-gathering tools on it, whether it be strain gauges or accelerometers, capture real-time load and vibration data from that system, and correlate it to our FE models,” Tanner explained. “We use that to drive our simulation – and to predict more that may happen.”

NVH simulation and analysis is “at the beginning of the power of what we can do,” Tanner said. “The tools are becoming more inter-connected and fully integrated, allowing us to run seamlessly from CAD to simulation to structural analysis to acoustics to vibration. The workflow is increasingly faster, enabling us to run multiple simulations in a single day. It used to take weeks.”
