Why is this exciting and important? This enhanced digital twin demonstrates a multi-domain system including fluids, electromechanical, electromagnetics and thermal aspects, coupled with a user friendly Human Machine Interface (HMI), to solve a challenging problem that faces motor designers and operators — determining, monitoring and maintaining the optimal temperature at which to operate the motor and its components on a consistent basis. Why does this matter? Every 10 degree Celsius increase in operating temperature of the motor and components over their optimum temperatures decreases the life of the motor by half!Continue reading →
Since the 1960s, Dr. Gordon Moore’s prediction that computing performance will double every 12 to 18 months has held true. More recently, the gains in computing performance have been enabled by a combination of hardware and software technologies, such as multi-core, multi-threaded designs. The conveniences of the modern world — ubiquitous communication through internet-enabled phones, electronic payments and digital streaming, to name a few, are partly due to continuous engineering innovations delivered through cheaper, faster, more-precise electronics.

The concept of the “automated home and smart home” was first introduced over 80 years ago, and has been facing different technical limitations since then.
Recently, service providers and home appliance manufacturers have launched a new initiative to bring the concept of smart homes to reality allowing subscribers to remotely manage and monitor different home devices from anywhere via smart phones or over the web with no physical distance limitations.

Digital twins, supported by sensors and communication infrastructure, are rapidly changing the business models at many companies and are expected to create trillions in global economic value. In 2014, at the 3rd Annual Minds & Machines Conference, General Electric Chairman and CEO Jeffrey Immelt declared, “If you went to bed last night as an industrial company, you are going to wake up in the morning as a software and analytics company.” He announced that GE would make its Predix operating system for powering the industrial internet to any company in 2015. Yet, despite the excitement that year data from Accenture shows that only 10 percent of market leaders understand the underlying business models and long-term implications of IIoT and digital twins.

For over 30 years, ANSYS has been supplying GE with sophisticated first principle modeling tools that have enabled virtual prototyping of some of the worlds most complex products. The relationship continues to mature as the two explore the marriage of GE’s Predix Platform with ANSYS’ Simulation Platform to create the potential to enhance the monetization of asset health monitoring and the industrial internet of things. This marriage further enables closed loop feedback with engineering to accelerate NPI and drive costly warranty costs out.
The ANSYS Simulation Platform utilizes a variety of parameters sensed, collected and sorted by the Predix Platform, parameters such as temperature, pressure and vibration to create a simulation based physics model that represents a digital twin of an asset that can be used to accurately predict asset health.

The Gartner Hype Cycle charts are a peek into the future. They graphically project where various technology trends are along a maturity timeline. The most recent Hype Cycle identifies several megatrends, including digital business technologies and new design and innovation approaches, such as IoT product design.
Antennas are the lifeblood of connected, mobile and many emerging IoT products. Consumers expect a reliable connection every time; anything short can kill a product launch or, worse yet, tarnish a corporate brand. That’s the market reality. The engineering reality is that there are significant engineering challenges associated with designing antennas and radio systems, including providing reliable connectivity and maintaining reasonable performance within an ever shrinking design footprint. Many of today’s devices need to operate in an increasingly crowded radio spectrum with the possibility of co-site conditions, operation near the human body and other challenging installed environments.

Last year marked the 200th anniversary of the battle of Waterloo. I recently read an excellent account of the battle by Tim Clayton. What a tremendous difference between the technology available to the soldiers and generals in those days compared with today’s connected soldier. Continue reading →
Every day we hear about a new internet-enabled product — or two, or three, or a dozen. Consumer products are increasingly more connected including appliances, automobiles and traditional electronics like smartphones and tablets. In the industrial world, factories, aircraft, distribution facilities, power plants and many other things are being monitored by sensors and communications networks to provide feedback on production, maintenance and efficiency. Importantly, these devices collect data that allow manufacturers to understand how products are used so that they can develop better things that more closely fit our needs. Engineers designing smart, connected products need to address competing and complex challenges, including size, weight, power, performance, reliability, durability. For example, engineers may need to design reliable sensors, high-speed communication and networking equipment, or supercomputers that process vast amounts of data. How can designers ensure that their products will work flawlessly in the real world? Continue reading →
Wireless power transfer (WPT) is much researched and discussed in the context of IoT, electric vehicles and mobile electronic devices. The methodology of powering a device without a physical connection is well known. However, designing the coil shapes and their placement, maximizing efficiency and validating behavior at the system level still represent challenges that cannot be achieved without simulation. The next frontier to be explored is extending and applying wireless power transfer systems to more applications, such as continuous charging of multiple devices, increasing the range of efficient power transfer and ensuring the WPT system design meets regulatory guidelines.
