Digital Twins/IIoT

Bringing the business benefits of engineering simulation (CAE) to the entire product performance life-cycle (PPL)

What are Digital Twins? Why Bother?

As is true with any emerging field of technology, Digital Twins is just now coalescing into a clearer definition of what it actually means in practice. Many market observers and vendors have offered up their views on what Digital Twins means to them. The ingredients have been around for a while, but their synergistic combination is just now bearing initial business fruit. Key enablers are the increasing accuracy of CAE models, the declining costs of high-performance computing, expanding cloud accessibility, and low-cost sensors.

    The Digital Twin concept is creating an opportunity for PLM providers. Top management of PLM user companies already believe PLM is the owner of Digital Twin technology. The opportunity is for PLM providers to take the lead in defining road maps which will guide their customers’ visions for Digital Transformation. This paper considers road maps in other sectors and Cambashi market data to suggest how PLM providers can elbow their way to the front of the queue.

    The Brain Neuromodulation project represents a breakthrough in demonstrating the high value of computational modeling and simulation in improving the clinical application of non-invasive electro-stimulation of the human brain in schizophrenia and the potential to apply this technology to the treatment of other neuropsychiatric disorders such as depression and Parkinson’s disease. With the addition of HPC, clinicians can now precisely and non-invasively target regions of the brain without disrupting nearby healthy brain regions.

    2018 Hyperion HPC Innovation Excellence Award: UberCloud, the National Institute of Mental Health & Neuro Sciences (NIMHANS) in Bangalore, Dassault Systèmes Simulia, Advania Data Centers, Hewlett Packard Enterprise and Intel won the 2018 Hyperion HPC Innovation Excellence Award for their Neuromodulation Project, based on computer simulations of non-invasive transcranial electro-stimulation of the human brain in schizophrenia.

  • Simulation Applications Enable Digitalization at ABB Traction Motors

    Industry 4.0 and digital twins are buzzwords we hear on a daily basis. But how far have companies come, and how does COMSOL come into play in the new era? Here, we will look into one successful case, where ABB Traction Motors intends to make mass customization available by using simulation applications for electric motor design. By turning high-fidelity multiphysics models into simulation applications, new analysis capabilities are planned to be available to several departments, from product design to sales.

    View SummaryGet Content

    ABB Traction Motors initiated a new project, called NG Design Tool, to create an easy-to-use software tool that could predict the temperature in a traction motor during different operation conditions and duty cycles. The project was led by Dr. Shafigh Nategh, R&D senior engineer and project leader at ABB Traction Motors. Experts and students from Politecnico di Torino in Italy, Chalmers University of Technology, and The Royal Institute of Technology in Sweden were invited to tackle this challenge together.

    “To be able to run projects with this level of engineering complexity, it is important to have the right tool partners. In ABB Traction Motors, we work with reliable tool suppliers supporting us to provide better service for our customers. We are happy that we have COMSOL on board in this project’’, says Dr. Shafigh Nategh. “Multiphysics simulation allows us to explore how different components work together; not to mention the ability to turn a high-fidelity model into a digital twin or simulation application.”

    COMSOL Blog (Ed Fontes): Digital Twins: Not Just Hype

    COMSOL Blog: "Is the term “digital twin” just hype, or a trick to get a new angle to sell modeling software? In this blog post, we discuss the difference between models, applications, and digital twins. We conclude that although the term has been misused to a certain extent (in relation to the original formulation), there is substance behind it."

    What Is a Digital Twin?

    One of the first industries to consider the use of digital twins is the aerospace industry. In a very insightful paper, Glaessgen and Stargel explain the use of digital twins for vehicle certification and fleet management. The digital twin for a vehicle would be used to “continuously forecast the health of the vehicle or system, the remaining useful life, and the probability of mission success.” The description of the digital twin is the following: “A digital twin is an integrated multiphysics, multiscale, probabilistic simulation of an as-built vehicle or system that uses the best available physical models, sensor updates, fleet history, etc., to mirror the life of its corresponding flying twin.”

    The term “digital twin” was coined by Michael Grieves at the University of Michigan in 2011.  The concept had already been formulated by Grieves in 2002, but was then referred to as a “mirrored spaces model.” In Grieves’s definition, the digital twin concept consists of a real space and a virtual space. The virtual space contains all of the information gathered from the real space. It also contains a high-fidelity description of the physical device or process from the microscopic level to the geometric, macroscopic level. The description provided by the digital twin should be “virtually indistinguishable from its physical counterpart.”

  • Virtual Sensors in Digital Twins

    "By definition, a virtual sensor is a type of software that, given the available information, processes what a physical sensor otherwise would. It learns to interpret the relationships between the different variables, and observes readings from the different instruments. Think of it as a kind of a “ghost” of the physical sensor." (from Chad Jackson)

    https://www.lifecycleinsights.com/what-is-a-virtual-sensor/

    “The idea here is that if you’re running a simulation and you’re getting accurate inputs, and it is mimicking the behavior of a product in real life, in real time, you can then instrument that simulation model with taking measurements at different locations. You are going to be getting readings from that virtual sensor, which is where you’re taking measurements, and then you can actually use that to complement physical sensors.

    WHY IS IT IMPORTANT?
    What’s great about this is you can place virtual sensors on a simulation model anywhere. That’s a lot different from what you see in the real, physical world. In many cases, you might not be able to place the physical sensor exactly where you want it to be.

    For example, think about locations with high radiation. You’re not going to be able to get close enough to place a physical sensor. It will be fried very, very quickly. Or maybe it’s a mechanical assembly, and there isn’t enough clearance where you want to place the sensor. Other factors that influence the decision to choose virtual over physical include cost and reliability.

    The Digital Twin can help deliver that, and you don’t necessarily have to be connected to take advantage of virtual sensors.”

  • CHAD JACKSON: ARE DIGITAL TWINS REALLY NEW?

    People have been feeding sensor data to simulations for years. How are Digital Twins different? This post explains the key difference between the two scenarios.

    View SummaryGet Content

    …when we’re talking about a digital twin, we’re after something very different. It’s about capturing sensor data from a product in real time and feeding it in real time to a simulation being solved in real time. That’s the biggest difference. It’s not done separately. It’s not done later. It’s being run in real time while the product is in use. We can learn how the product is being used, and in what ways it might be failing.
