What Is Digital Twins/IIoT?

What are Digital Twins? IIoT? 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.

What is IIoT? IoT (Internet of Things) is just connecting physical devices/systems to each other via the internet (think: your home internet-connected thermostat and an app on your smartphone that enables you to observe and change the temperature in your home from anywhere on earth if you have an internet connection). If the devices and connections and data transfer via the internet are for business/industrial systems, that’s the INDUSTRIAL Internet of Things. A lot more detailed and involved, but the same basic idea. When one of the “things” is a current/updated physics/simulation-based digital model, that’s where IIoT plays a role in Digital Twins.

Some Digital Twins Definitions

This “How It Works” area of the Revolution In Simulation website is your go-to source for more in-depth background information on Digital Twins and the latest relevant end-user enterprise and vendor case studies and success stories.

Physics-based simulation models (CAE) have proven their mainstream  business value during the development and manufacturing phases of the Product Performance Life-cycle (PPL).

Now they are moving beyond those phases into the entire life cycle of products and systems by being updated/modified to reflect the ongoing true in-field status/condition of such products and by being subject to the actual in-field loadings and boundary conditions obtained from sensors (the Industrial Internet of Things – IIoT). The resulting Digital Twins can then be used to anticipate needed maintenance and predict the behavior of future proposed operational changes to the physical structures and systems they represent in digital form.

Make an impact in the real world with Digital Twins

Let's discuss the importance of keeping your digital twins in sync with real products. Models so accurate they’re a digital twin of the product you’re creating can help you throughout the design and development process. 1D models can help you determine the best architecture for your multi-physics system, 3D models can help you design into the details, and testing can help you improve modelling realism. Combining all the three technologies gives you the highest possible accuracy while making design decisions. But in today’s world the design job isn’t done when you ship. You have to be able to take feedback, track how products are used – with detailed data coming from the increasing numbers of sensors in modern devices – and then use that to support, maintain and improve the products you have out in the market, as well as incorporating all that information into your next generation. That means keeping your digital twins in sync with the real products, even once they’re in customers’ hands.

Could Digital Twins remove doubt from due diligence during M&A?

Innovation and new technology applications are being established as part of core business management tools and are starting to appear in the area of managing M&A. When M&A is announced, organisations are committing to buy an asset or asset groups – at which point a due diligence effort is usually conducted to establish the actual state of the asset. Digital Twins have shown significant promise for the management of assets, and could also be transformational in the M&A process to qualify the quality of the assets.

Digital Twins in the Hot Seat: Realizing Great Expectations

PREVIOUS WEBINAR AVAILABLE ON DEMAND The phrase “digital twin” has become the be-all-and-end-all of manufacturing buzzwords, stirring up Utopian views on what it can do for predictive maintenance, simulation and more. But how is a digital twin different from a 3D CAD product model? Can it ever live up to its full potential? Is anyone really making use of digital twins? In this LIVE webcast, DE challenges panelists to discuss: a no-nonsense definition of digital twins; the types of products that make sense as digital twins; real-world examples of digital twins in operation.

How to Quickly Create a Simulation-Based Digital Twin of an IIoT-Connected Product

Digital twins are virtual representations of physical products. They have the ability to unlock value and optimization throughout a product’s lifecycle. By leveraging real-world data from IIoT-connected product and physics-based simulations, digital twins can better inform and predict product performance. This enables users to develop new designs, operations and controls to optimize performance, reduce downtime and enable service-based products — often without the customer needing to upgrade hardware. The technology to get an IIoT digital twin running is available, however, many organizations are having a hard time implementing and connecting all of the digital, physical and data assets together. With the help of ANSYS Twin Builder and PTC ThingWorx, engineers can simplify the creation of digital twins using physics-based simulations.

Why digital twins will be the backbone of industry in the future

For industry and the internet of things (#IoT), digital twins, offering virtual representations of real-world products will be the innovation backbone of the future. Entire systems can be simulated and tested long before a physical prototype has been built. Even operation of existing systems can be further optimized using a #DigitalTwin. Imagine the extraordinary possibilities merging them with artificial intelligence (#AI). Industry experts for digital twins are already using all these possibilities in concrete applications.
