3751. Hybrid 3D-1D Models for Particulate Systems

      NAFEMS Americas hosted its biennial regional conference, formerly known as CAASE, on June 21-23, 2022, face-to-face, at the Indiana Convention Center in Indianapolis, Indiana! The NAFEMS Americas Regional Conference 2022 (NRC22 Americas) brought together the leading visionaries, developers, and practitioners of CAE-related technologies in an open forum, unlike any other, sharing experiences, discussing relevant trends, discovering common themes, and exploring future issues, including: What is the future for engineering analysis and simulation? Where will it lead us in the next decade? How can designers and engineers realize its full potential? What are the business, technological,...more

3752. How Do You Know if you are Executing the Right Simulations at the Right Time?

      Analytical modeling and simulations are a part of most companies' product development process these days. Typically, there are a group of highly specialized CAE analysts that perform various physics-based simulations that consume significant budget resources, and time. If done correctly, the simulations are typically conducted early in the development phase in order to determine if a proposed solution will work under the desired boundary conditions. However, this may not be the case if your company is resource limited or directs most of the CAE resources to use simulations to assess post-test failures. Model-based Systems Engineering (MBSE) processes have been implemented within the product...more

3754. How to Tell the Difference Between a Model and a Digital Twin

      “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...more

3758. Where Do We Get the Courage to Sign the Blueprint?

      In this webinar the sources of error in numerical simulation and methods used for controlling them will be discussed. It is shown that when the size of the numerical errors in the quantities of interest (QoI) are not known then it is not possible to certify that a design is in compliance with the design rules. Therefore error estimation in terms of the QoI is an essential technical requirement. Error estimation is possible only when the mathematical model is properly formulated. This webinar will also highlight the differences between finite element modeling and numerical simulation. The creative aspects of formulating mathematical models and objective methods for ranking their performance are...more

      Digital Twin – An Engineers’ Perspective Abstract The term “Digital Twin” was defined by Dr. Michael Grieves at the University of Michigan around 2001. He defines “Digital Twin” as a digital replica of physical assets, processes and systems that have been manufactured. He promoted the idea of comparing a Digital Twin to its engineering design to better understand what was produced versus what was designed, tightening between design and execution. Digital Twin starts with the existence of a physical part –as early as a prototype exists, and they last until product end-of-life. We can put the digital twin life into three major phases: twins for designs, twins for manufacturing and twins for...more

3760. Blog: How Do I Switch It On?

      Blog: How Do I Switch It On? Excuse me, how do I switch it on? 19 March 2013 by Tony Abbey, NAFEMS Training Manager One of the most enjoyable aspects of the training that I carry out is the travelling involved. I have been very fortunate to teach in many countries around the world and to visit many interesting places. Often this involves flying into an airport, picking up a rental car and then heading off to my hotel on the first night. One of the great blessings has been the introduction of SatNav or GPS navigation aids. I always carry my own with me and like to have a backup iPhone or similar just in case. Finding a city centre, or very rural, hotel on a dark rainy night is now a lot...more
