Engineering with Digital Twins as Part of Data Week 2021
This session explores the fundamentals of digital twins in an environment where equipment integrity, operation, and safety are traditionally supported by engineering simulations.
Backed by a wealth of experience across industries, we will cover how it works, benefits, challenges, and tips on doing it successfully, with Q&A. We particularly welcome questions about challenges from your industry. No expertise required to attend.
Engineering simulations help us turn information we have into information we want, to help us make decisions. In this context, these decisions might be about when to carry out maintenance, or when to replace equipment. This reduces cost, as equipment can be run longer or in more extreme conditions; it can improve safety, reducing the likelihood of unexpected failure.
High degree-of-freedom models can provide accurate simulations of systems from first principles, such as FEA, CFD and EM solvers. With the right validation, these provide effective ways of turning selected input data into more useful data for life predictions. The issue with these is usually one of speed, limiting the use of simulations to single case analyses or short selections.
An engineering simulation can be seen as an expensive and complex mapping function, taking a small set of inputs to deterministically produce a large set of outputs. Treating the complex simulation as a ‘grey-box’ control system, pulling together techniques of system classification, machine learning, data-driven methods and classical engineering physics, a minimal alternative to the mapping function can be found: our Reduced Order Model or Digital Twin. These can drastically reduce simulation times to generate new results from new inputs, from hours to milliseconds.
This physics-based approach to system classification is key to providing confidence in safety, particularly in a regulatory environment.
The speed of these methods opens the possibilities of new outcomes, such as real-time monitoring and probabilistic assessments. Counter-intuitively these simple models, when used right, can increase the fidelity of predictions.
