NAFEMS Seminar - Trends and Best Practices for Digital Twins, SPDM and more!
NAFEMS is the International Association for members of the Engineering Modelling, Analysis and Simulation Community. As an independent authority, it establishes best practice in engineering simulation by focusing on the practical application of numerical engineering simulation techniques including finite element method for structural analysis, computational fluid dynamics and multibody simulation.
The bulk of NAFEMS’s technical activities are coordinated and undertaken by specialist technical working groups made up largely of NAFEMS members including top academic researchers, engineering practitioners and software vendors. These working groups identify, via surveys and the personal insights of committee members, those areas of interest that require new educational materials to be developed in the form of NAFEMS publications.
This NAFEMS collateral event features speakers from some of these working committees who will be sharing their pointers for the engineering community in the areas of computational structural mechanics and simulation data management.

Presentation: How to Tell Difference Between a Model and a Digital Twin by Louise Wright
“Digital twin” is currently a term applied in a wide variety of ways. Some differences are variations from sector to sector, but definitions within a sector can also vary significantly. Within engineering, claims are made regarding the benefits of using digital twinning for design, optimisation, process control, virtual testing, and lifetime estimation. In many of its usages, the distinction between a model and a digital twin is not made clear.
"When I use a word, it means whatever I want it to mean": Humpty Dumpty in Alice’s Adventures Through The Looking Glass, Lewis Carroll.
The danger of this variety and vagueness is that a poor or inconsistent definition and explanation of a digital twin may lead people to reject it as just hype, so that once the hype and the inevitable backlash are over the final level of interest and use (the “plateau of productivity”) may fall well below the maximum potential of the technology.
The basic components of a digital twin (a model and some data) are generally comparatively mature and well-understood technologies. Many of the aspects of using data in models are similarly well-understood, from long experience in model validation and verification and from development of boundary, initial and loading conditions from measured values. However, many interesting open questions exist, some connected with the volume and speed of data, some connected with reliability and uncertainty, and some to do with dynamic model updating.
In this speech the essential differences between a model and a digital twin will be highlighted, outline some of the key benefits of using digital twin technology, and suggest directions for further research to fully exploit the potential of the technology.

Presentation: Applications of SPDM in Aircraft Structural Analysis at Embraer by Rodrigo Britto Maria
For finite element analysis (FEA) of a structure such as an aircraft, the model needs to be decomposed so each team can concentrate on its specialized domain — the fuselage, wings, or control surfaces — with the appropriate level of details. Ensuring that the design changes made at the component level are faithfully recorded and accounted for at the system level is often a challenge. Simulation processes used to analyze these design changes are composed of chained applications that generate a sea of digital information. It's not feasible to manually keep track of the connections among all the digital artifacts generated by those processes. You can effectively manage the cascading changes and the dependencies among all the digital artifacts using the Simulation Process and Data Management (SPDM) technology. In this presentation, you'll hear about the proven strategies deployed at Embraer to: Increase simulation throughput; Improve data traceability; Standardize and automate the simulation processes.
Membership with NAFEMS by Paul Steward
In this presentation Paul Steward comments on how effective the NAFEMS membership solution is, how this delivers value and benefit to all organisational profiles within the engineering analysis and simulation industry. Covering over a NAFEMS reaction to the global pandemic with support for existing and new members, Paul shares valuable feedback from members as to why they are participating within the community and what membership means to them. Paul also highlights some new content available to the community and how they can embrace NAFEMS support

National Physical Laboratory & NAFEMS Computational Structural Mechanics Working Group
Louise Wright leads NPL's continuous modelling work, applying numerical techniques such as finite element (FE) methods, finite difference methods, boundary element methods and meshless methods to metrology problems from a wide range of areas of physics, including static and dynamic stress analysis, heat transfer, and acoustics. She is interested in optimisation and uncertainty evaluation applied to finite element models, particularly for use in improving confidence in FE as a design tool.
She is also interested in methods of integrating measurement data into models to enable estimation and uncertainty evaluation for parameters and initial conditions. This task feeds into the idea of a “digital twin”, which uses a combination of data gathered throughout a system’s development and lifetime and a validated model to deliver high accuracy predictions of system performance with associated uncertainty quantification.
Louise received an MA in Mathematics from Cambridge University in 1994, and an MSc in Mathematical Modelling and Numerical Analysis from Oxford University in 1995. She spent four years working with FE in industry before joining NPL in 1999. Louise is the chair of the NAFEMS Working Group on Computational Structural Mechanics, a member of the NAFEMS Working Group on Stochastics, and is a founding member of the NAFEMS Professional Simulation Engineer certification scheme.
