Digital Twin Technology: Reduced Order Modeling In the Field

Alan McKim, SimuTech Group’s Vice President of Test Engineering and QAIn a recent blog post, SimuTech Group’s President Rick James wrote a high-level overview of Digital Twin, and explained its significant economic impact. Today, SimuTech Group’s Vice President of Test Engineering and QA Alan McKim takes a practical view, discussing how--with help from Reduced Order Modeling (ROM)--Digital Twin works in equipment testing. He also illustrates how SimuTech Group used Digital Twin technology to help a customer gain insight and resolve performance concerns.


Though there’s a lot of discussion about Digital Twin technology, some engineers and designers find it difficult to understand how it can economically impact them. Here’s an analogy that might help illustrate the digital twin concept: equipment used in the field could be compared to staff working in a remote location. You need to communicate regularly with these staff members to solve issues. Imagine a staff member dealing with an issue, but not communicating information back to you. This would cause delays, reduced performance, or potentially even ultimate failure of the offsite effort.

your employee on a deserted islandYou wouldn’t place your employee on a deserted island with no means of communication so why do it to your equipment?In a similar way, equipment has generally been left on its own in the field. However, technology has simplified the ability to gain information about equipment during its operation. Sensors can easily be installed to gather data about temperature, vibration, or load indication--all valuable in determining how the system is performing in its environment. Going back to the analogy: the communication with offsite humans is relatively direct; their communication is understood directly. However, when equipment sends sensor data, this must be interpreted.

This is where mathematical Reduced Order Models (ROMs) come in. With an ROM, you can take the critical aspects of a detailed model and reduce them down to simpler equations or algorithms that can be used in real time. Most engineers are familiar with detailed computer simulations that take hours or days to run. However, with field information, you do not want to wait hours or days to understand the implications. An ROM is the simplification of the input to output of a complex model. You still need the detailed model to generate this relationship, but once it is known, the ROM can be used.

While a Digital Twin is often perceived as a massive undertaking, it doesn’t have to be. Referring back to the analogy of staff working in the field: you may need to deploy a single person, or a group of 100. The same is true for Digital Twin technology, which can be large and broad with lots of details, or narrowly tailored.

Add Granta MI to your toolbox for instant materials information

Granta MIFor the first time, engineers can gain instant, accurate access to the Granta materials database within ANSYS Workbench™, speeding up their materials selection and improving their workflows.

In late 2018, ANSYS, Inc. acquired Granta Design, the premier provider of materials information technology. Through the MI:Materials Gateway window within ANSYS Workbench, you can access validated materials information in several categories, including steel, plastics, and aerospace.

If you know which material you’re looking for, you can select it directly. Or you can search with keywords like “aluminum 6061,” and the material’s property datasheets will be shown to you. You can also ask Granta to show you materials with defined specs, like yield strength above or below a certain value. You can then compare and contrast different materials.

New ANSYS Cloud Provides HPC As Easy As It Should Be

ANSYS Cloud - HPC as easy as it should be

In the last few years, engineering challenges have become more complex, demanding more and more computing resources. On-premise hardware and processor capabilities aren’t always enough for companies to perform the rapid, sophisticated product design and analysis they need to do in order to develop their best products. ANSYS Cloud computeDue to internal IT constraints, engineers may have to wait in line for computing resources, or limit the scale and complexity of their simulations.

ANSYS Cloud offers a solution. For the first time, engineers can quickly tap into the power of cloud-based High Performance Computing (HPC) whenever they need it. Current users of ANSYS Mechanical™ and ANSYS Fluent® can submit their project to the cloud, and then monitor it from their desktop, a web browser, or even a mobile device. Because your needs may vary day by day, cloud computing can save you money, providing the computational power only when it’s needed. More freedom to use multiple physics and fine meshes can increase the accuracy of your results, and time-to-market can be accelerated.

ANSYS Motion - a New Dedicated Multibody Dynamics Tool

Our clients working in multibody dynamics and kinematics have an outstanding new simulation tool: ANSYS Motion.

ANSYS Motion can help engineers…

  • Find more accurate boundary conditions during static analyses
  • Solve big deformation problems while incorporating non-linear material properties
  • Perform kinematic analyses of mechanical systems
  • Analyze high-speed rotation problems with complex geometry

Tightly coupled rigid and flexible solvers that are powerful and fast allow engineers to study situations beyond what is possible in ANSYS RBD (Rigid Body Dynamics). Modal flexible, meshed flexible, and rigid parts can be tied together with standard joints and connections so accurate loadings on the components can be calculated.

This standalone solution for multibody dynamics and flexible multibody dynamics uses its own pre- and post-processor and solver. Pre-processing is integrated into ANSYS Mechanical via an ACT extension.
