If you weren’t in Salzburg, Austria, on June 9-12, you missed what is arguably the best vendor-neutral global conference and exhibit dedicated solely to engineering simulation (generally called CAE for short and consisting of finite element structural analysis methods, computational fluid dynamics, multibody dynamics, electromagnetics, co-simulation, and related data and workflow/process management). Approximately 560 people managed to make it there, despite record flooding nearby in Germany, and they participated in an event that surely exceeded their expectations (as it did this author’s).
The 14th NAFEMS World Congress (NWC), sponsored by Dassault Syst mes/SIMULIA and nine other major vendors, contained four days of keynotes, plenary sessions, and parallel topical tracts, complemented by exhibits from 40 of the leading CAE vendors, short courses on the most important CAE topics, and plenty of opportunities for networking with existing CAE colleagues and meeting many new ones. Oh, and last but not least, the NWC was held in the modern Salzburg Conference Center, with some great social events and sightseeing opportunities in one of the most charming cities in Europe.

NAFEMS, founded in 1983 and headquartered in the UK, with regional chapters in the UK, France, Germany/Austria/Switzerland, Italy and the Americas (where this author is a member of the regional Steering Committee), is the largest vendor-neutral, not-for-profit association with the focused mission to promote the effective professional use and benefits of engineering simulation. This is accomplished through a growing number of publications, training courses (both classroom and e-learning), participation in government-funded research programs, and regional conferences. The capstone is the biannual World Congress, which alternates between Europe and the Americas. From 1987 onward, in venues such as Paris, Orlando, London, Boston, Vancouver, Malta and Greece, the World Congress has seen a steadily growing attendance, with 2013 breaking all previous records.
More than 1,100 member organizations, representing industry, government and academia from dozens of countries, belong to NAFEMS. The backbone of NAFEMS’ value and output comes from a growing number of topic-focused volunteer professional working groups, who meet regularly (greatly aided now by the power of the Internet for high-quality virtual meetings) and identify the key issues within their specific topics, develop corresponding white papers, and issue requests for quotations (RFQs) for related “How To” guides and handbooks to be created and published under the NAFEMS banner. The Working Groups form the basis for the choice of World Congress topical tracks and solicitation of presentations, including full published papers available in hyper-linked PDFs on a DVD for all attendees. If you missed the event in Salzburg, you can purchase the complete Proceedings DVD from NAFEMS.
This year’s World Congress, incorporating the First International Conference on Simulation Process and Data Management (SPDM), had plenary sessions each morning, followed by parallel topical tracks consisting of the following:
- Aerospace applications
- Automotive applications
- Biomedicine applications
- CAD/CAE integration
- Civil engineering applications
- Computational fluid dynamics (CFD)
- Contact problems
- Dynamics and testing
- Emerging issues: high-performance computing (HPC)
- Fluid-structure interaction (FSI)
- Industrial collaboration
- Joints and welding
- Multi-body systems
- Multiphysics (MP)
- Noise, vibration and harshness (NVH)/acoustics
- Open source software
- Optimization: shape, parameter, multidisciplinary, multi-objective
- Professional simulation engineer (PSE)
- Simulation automation
- Structural dynamics
- System simulation
- Thermal simulation
- Verification and validation
The plenary keynote presentations on the first day emphasized the leading importance of CAE in the automotive industry. Ralph Sundermeier, Ph.D., head of automotive interior simulations and the simulation methods development group at Volkswagen’s headquarters in Wolfsberg, Carinthia, Austria, talked about “Frontloading by Calculation: Evolution or Revolution?” He emphasized the growing role of simulation with much less product definition data ” that is, well before the availability of detailed CAD models.
Sundermeier made a good case for the need for a “revolution” to reach the full potential of CAE in the next five to seven years. He showed that the growing role of the automobile as a mechatronics product requires co-simulation of complete vehicle functional requirements, and thus method coupling and co-simulation will drive the required revolution. Sundermeier presented numerous practical VW examples to prove his points.
CAE and the Cloud
Frank Popielas, director of Dana Corp.’s global CAE efforts and a member of the NAFEMS Americas Steering Committee (NASC), reviewed the CAE market needs and drivers from Dana’s perspective, where CAE is now a mainstream resource allowing a significant traditional supplier like Dana to become a development partner with its major automotive and related original equipment manufacturers (OEMs). He discussed how the emerging visual intuitive environment (no longer requiring manuals to learn), coupled with the Cloud, will provide a virtual desktop for performing and reviewing CAE on the road wherever CAE engineers have Internet access: “The world of iCAE is around the corner.”
In connection with the growing interest in mechatronics and co-simulation, Popielas also mentioned the new formal partnership between NAFEMS and the International Council on Systems Engineering (INCOSE), which was announced last year and further defined with two topical sessions on systems engineering at the NWC. NAFEMS and INCOSE have created a joint Systems Modeling and Simulation Working Group (SMSWG). Popielas is the NAFEMS Chair of this Working Group, which will hold its first meeting at the INCOSE International Symposium in Philadelphia on June 25.
The plenary presentations on Tuesday, June 11, included:
- An aerospace-focused talk by J ©r me Buffe, head of the mechanical department of the French company Thales Alenia Space’s Platform and Integration Competence Centre, on optimizing the validation process via coherence of analytical and test justifications.
- An excellent overview titled “CAE in Japan: Now and Then” by Koichi Ohtomi, Ph.D., of Toshiba. His presentation included comments on the first steps to bring NAFEMS more formally into the Japanese CAE world via cooperation with the Japan Society for Computational Engineering Sciences (JSCES) and the Japan Society of Mechanical Engineers (JSME). JSCES has 900 members and an annual conference, and the Computational Mechanics section of JSME has 5,400 engineers, making it the largest CAE organization in Japan. Ohtomi emphasized “1DCAE” as a focused effort on preliminary, conceptual design simulation.
PSE Designation Introduced
Perhaps the most strategically significant presentation at the NWC was when Tim Morris, CEO of NAFEMS, formally introduced the new Professional Simulation Engineer (PSE) designation and scheme. This author, a 40-year career veteran of research, teaching, development and executive management in CAE, is particularly pleased to see this important step in elevating the hard-earned professional status of at least one branch of the modern engineering world.
The PSE is the result of extensive work by NAFEMS Working Groups, funded in part by the European Community, to structure the elements of today’s simulation engineering work, provide a mechanism for tracking relevant engineering competencies, and finally certify simulation engineers where such certification would aid both employers and employees who do important simulations as part of their engineering work. More details on the PSE may be found at the website NAFEMS.org/pse.

Further plenary presentations on Wednesday, June 12, included:
- “Replacing Test with Simulation in Highway Safety ” The Tata Steel Journey,” by Steven Sirman of UK-based company Tata Steel Automotive. His presentation contained some excellent video comparisons of simulation results and full-vehicle barrier crash tests.
- “Structural Optimization in the Early Development Phase at Volvo Cars,” by Harald Hasselblad, Ph.D., of Swedish automotive manufacturer Volvo.
- “50 Years of Stress,” an excellent personal retrospective of a full and outstanding career in academic teaching/research and commercial software development in CAE by Professor Grant Steven of Australia’s University of Sydney.
- An overview by Paul Newton, Ph.D., of the NAFEMS Governing Council, of the initial results from the approximately 1,000 respondents to the recent customer survey conducted by the NAFEMS Vendor Advisory Board (VAB). This is the first concrete product of the newly formed VAB (which was organized and launched at the NWC in 2010 in Boston by this author), and bodes well for the future efforts of the VAB.
The hundreds of excellent presentations made during the many parallel tracts at the NWC are way too numerous to even summarize here. The reader is encouraged to take a deeper look at the NWC Agenda at NAFEMS.org for more details, where complete presentation proceedings of all papers (PDFs on a DVD) may also be purchased.
A couple of the parallel track sessions are, however, worth mentioning here. The two sessions on Systems Engineering, chaired by Frank Popielas and this author, included Sven-Olaf Schulze, Chair of INCOSE-Germany, who presented an overview of INCOSE for NAFEMS, and Ed Ladzinski of Dassault Syst mes, also a member of the NASC and the originator of the idea for the cooperation between INCOSE and NAFEMS, who presented the activities and motivation leading up to the formal NAFEMS-INCOSE partnership. There were also four sessions on the popular emerging issues of HPC and “The Cloud” (including a presentation by this author on the UberCloud HPC Experiment) and one on the controversial topic of open-source software.
If you weren’t in Salzburg, you missed a lot, but you have a chance to make it up by attending the next NAFEMS World Congress in the Spring of 2015 in the U.S. We hope to see you there!
