3901. Informing Model End-Users in Industry on the Credibility of Predictions

      Overview Modeling and simulation (M&S) are a well-established part of the engineering design process. M&S are also gaining traction in other product life cycle processes through concepts like certification-by-analysis and digital twins. These advancements and the widespread influence of M&S continue to add relevance to the question of how much to trust computational model predictions. The answer to this question can be extremely challenging to determine and strongly depends on the application. Even if there is Verification, Validation, and Uncertainty Quantification (VVUQ) evidence to build credibility in the model predictions, this information is often difficult to convey to the model end-users...more

3902. 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

3903. 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

3904. Simulating Metal Forming Processes – Material Characterisation

      Metal forming simulations are increasingly adopted by manufacturers to improve the quality and performance of products and processes while shortening development cycles so that these products can be brought to market earlier. Successful simulation of metal forming processes requires a range of input data about the geometry of the workpiece and tooling, the process forces and tooling motion and, above all, the characteristics of the workpiece material. The accuracy of the results depend on having a good understanding of this input data. In this webinar we introduce manufacturing process simulation methods for a range of metal forming operations and then review the material characterisation requirements...more

3905. Exploding Dough And Fun With Carrots

      Exploding Dough And Fun With Carrots by Tony Abbey, FE Training Welcome to my first blog for NAFEMS and an unusual title. It has been a very busy two weeks travelling and teaching the NAFEMS “Introduction to FEA” class in the UK and Holland. As usual each class was very different - depending on the background of the client company and the individuals attending. Both classes were fun, I always enjoy meeting fellow engineers and talking about FEA and engineering. Two or three days working with a group gives a great opportunity to find out about everyone’s background, what aspects of analysis they are involved with and the engineering behind the products or process. It is a privilege to have...more

3906. What About Quality?

      Presentation made by O. Widlund, M. Stallgard, J. Ask at the NAFEMS Nordic Conference 'Engineering Simulation: Best Practices, New Developments, Future Trends' that was held in Gothenburg, Sweden on 10-11 May 2016....more

3907. V&V Process across Structural Simulation in Airbus Operations

      Presentation made by J. L. D. L. Gandaraat the NAFEMS Spain Seminar "Verification & Validation - Building Confidence in Simulation for Engineering Design" that was held in Madrid, Spain on the 18th of February 2016. Seminar Description It is becoming increasingly important these days that engineering simulation used for design answers the question: how do we know that the results are reasonably correct? The important quality assurance tools used to answer this are the processes of verification and validation and these need to be applied to the conceptual, mathematical and computational models used in engineering simulation. In simple terms verification is the demonstration that the mathematics...more

3908. Sponsorship Opportunities

      Sponsorship Join us NAFEMS would like to extend an invitation to your company to be part of this conference focused on delivering information and insights on critical topic areas related to engineering simulation. Sponsorship of "Confidence in Engineering Simulation: The Next 10 Years of CAE in Mexico," offers a unique opportunity for maximum exposure to a highly targeted audience of delegates, who are all directly involved in engineering analysis and simulation. Team with NAFEMS As the International Association for the Engineering, Modeling, Analysis and Simulation Community, NAFEMS is widely recognized as the leading independent source of information and training for engineering analysts...more

3909. How To Use STEP Geometry for Engineering Analysis

      How To Use STEP Geometry for Engineering Analysis Due to the evolving nature of the engineering analysis and simulation market this publication no longer represents current best practice and has been archived. The document may be of historical interest and is therefore still available for purchase This guide is aimed at system managers who are implementing and supporting data exchange by purchasing STEP interfaces and users who want to communicate with customers and/or suppliers about using STEP for data exchange. The guide covers: What STEP interfaces are available What the parts and conformance classes cover How to choose which part and conformance class...more

3910. Renewal & Upgrade

      Renewal Any assessment resulting in certification has limited currency. When granted, certification is valid for a period of three years. Three years from the date of certification individuals who are registered PSE will be contacted by the PSE Administrator and asked if they would like to remain on the PSE Register. Candidates have three options: Candidates who wish to remain on the PSE Register and maintain their existing Technical Areas and level of certification are required to submit a PSE renewal form and confirm how they are maintaining their Continuing Professional Development. Candidates who wish to remain on the PSE Register and extend their range of Technical Areas or level of...more
