NAFEMS North America Conference '12

North America Conference 2012

NAFEMS, the premier global organization dedicated to the advancement and improvement of engineering simulation, hosted the 2012 North America Conference just outside of Washington D.C. on September 11-12, bringing together the leading visionaries, developers, and practitioners of CAE-related technologies and business processes to share relevant trends and roadmaps, to explore common themes, and to address these issues in an open forum. The Conference’s goal was to provide attendees with insightful content and perspective on how to position their organizations to realize the full potential of CAE.



Pathway to Future Virtual Product Creation in the Coming Intelligence / Convergence Era
Ahmed K. Noor, Old Dominion University

Dr. Noor's presentation will identify some of the characteristics of the coming intelligence/ convergence era, future complex adaptive systems, and their implications on virtual product creation.The need is described for establishing an Intelligent Cyber-Physical Ecosystem for facilitating interdisciplinary collaborations among engineers, researchers, scientists, software developers and other stakeholders working on the development and applications of the new interdisciplinary fields and the future complex adaptive systems. The new interdisciplinary fields will yield critical advances in engineering practice, and help in addressing future challenges in broad array of sectors, from manufacturing to energy, transportation, climate, & healthcare. They will stimulate creativity and innovation; invigorate engineering education, accelerate the development of skilled workforce needed in the new era. The major components of the ecosystem will be identified in Dr. Noor's presentation.

Manufacturing Tomorrow...Today
Jon Riley, VP of Digital Manufacturing at NCMS

Jon Riley’s presentation will consider the future of manufacturing and how engineering simulation will enhance and facilitate innovation in North America. As Vice-President of Digital Manufacturing at NCMS, Jon Riley will provide a unique insight into manufacturing across a wide range of industries.



CAE and its Role 2020 and Beyond for the Engineering Community
Frank Popielas, Dana Holding Corporation

The current state of the global economy is being discussed in quite a few papers,especially the role of CAE for the engineering community. The selling price is not the main and only driver to a product’s competitiveness any more. Being competitive means much more then that nowadays, it includes engineering support structure towards the customer, engineering support technology, time-to-market, quality guarantee at any point in time, product information access any time and, of-course,development and product costs. This presentation will discuss CAE, or better, an optimized virtual infrastructure as the only solution to achieve this.


Physics-Based Simulation: Helping Shape Future Cat Products
Larry Seitzman, Caterpillar

A company's product development process is responsible for delivering to the market the product the customer wants while satisfying the expectations of the company's shareholders. As the market moves faster and the products become more complex,the use of physics-based simulation is critical to achieving this combination of success factors. In this presentation, Larry Seitzman will discuss Caterpillar's journey towards Virtual Product Development and some of the challenges Caterpillar face getting simulation accepted into the product development community and the nextsteps in organization's journey.


Set Based Design Methods with Respect to Design Synthesis and Analysis Tools
Norbert Doerry, Naval Sea Systems Command

SBD can be thought of as design by elimination. One systematically decides the regions of the possible design space that are NOT the answer, then analyzes in more detail the remaining design space to see what additional area of the design space can be eliminated. Ideally, the remaining possible design space will shrink as the amount of detail required to support the next design space contraction decision increases (resulting in roughly the same amount of design work per "iteration") Eventually you end up with a feasible design space from which you can pick an arbitrary solution. This contrasts with the more traditional approach of trying to initially pick a winner and marginally modify if when more detailed analysis reveals problems. Norbert Doerry's presentation will explore how design decisions are made to Set Based

Design(in contrast to a more traditional Point Based Design) and how SBD challenges Design and Analysis Tool developments.

Making Simulation Business Relevant
Chad Jackson, Lifecycle Insights

There's little doubt that simulation and analysis is a highly technical engineering field.It is not, however, devoid of business relevance. In fact, these tools and technologies can have a profound impact on the effectiveness of the engineering organization.Based on his recently published eBook, The Engineering Manager's Survival Guide,Chad Jackson will talk about how initiatives such as Just-in-Time engineering and Agile Product Development are directly supported by specific simulation and analysis technologies like SPDM, topology optimization and more.


Regulatory Perspectives on Computational Modelling
Tina Morrison, Food and Drug Administration

Computational modeling has been recognized by the Center for Devices and Radiological Health as an innovative tool for advancing medical device evaluation and regulatory science. One of the strategic priorities for 2012 is the development of a Public-Private-Partnership centered around advancing regulatory science with computational modeling. Many efforts are underway to help further this initiative,including projects to collect data on boundary and loading conditions. Thus, the goal of Tina Morrison;s presentation is to highlight the current uses of computational modeling in device applications, present some of the challenges and limitations, and discuss what we can do as a community to advance regulatory science with computational modeling.

Computation, Measurement, and Standards
Andrew Dienstfrey, NIST

Scientific computing is increasingly used to inform decision-making in science and engineering, commerce, and policy. However, there are indications that in some cases critical qualities of these computations—for example, their reproducibility, and quantitative statements of accuracy and confidence in their outputs—are insufficiently characterized and understood. In this presentation, Andrew Dienstfrey will discuss research within NIST to address these challenges by presenting scientific computation as a new form of measurement. As such, it is anticipated that, in consultation with a broad cross-section of stakeholders, a uniform practice of uncertainty analysis and accuracy standards for scientific computing may be defined and promoted. Preliminary applications of these ideas in the areas of computational benchmark problems and medical device simulation will also be presented.
