We host over 60 independent events every year focused on the issues
and trends in engineering simulation
World CongressNAFEMS World Congress is a biennial global conference which has been a fixture on the
simulation calendar for 30 years.
Bringing together the international community in a neutral forum the last Congress in Stockholm attracted over 600 attendees including industrial users, software
vendors and academics.
ConferencesThroughout the year, NAFEMS holds a number of conferences
including dedicated regional and specific events across the globe.
SeminarsSeveral seminars are hosted every year focusing on current areas of interest as well as emerging topic areas.
WebinarsOnline webinars take place frequently allowing members to attend our events, no matter where in the world they are.
NAFEMS members benefit from seminar credits enabling many events to be attended inclusive of membership. Members also receive significant discounts on our World Congress and Training.

NAFEMS Publications
22
NAFEMS has published over 200 analysis and simulation publications. We are widely acknowledged as the premier source for analysis and simulation information.
Every year we produce approximately 8-10 new publications including textbooks, reports, benchmarks and journals.
NAFEMS members receive a library of their chosen publications when they join. Discounts are also available on additional publications.
In addition, members receive copies of all new publications as and when they are produced.

NAFEMS Publications
23
The international magazine for engineering
designers and analysts, Benchmark has
commanded respect for being the only truly
independent magazine specifically focused on
analysis and simulation.
Available exclusively to NAFEMS members, an
optional e-Library subscription gives instant
access to over 140 of NAFEMS publications.
NAFEMS Members receive copies of Benchmark magazine every quarter as it’s
published.
Members can also subscribe to our e-Library service to ensure they have
access to the information the need, when they need it.

PSE Competencies – A New Standard
PSE (Professional Simulation Engineer) competencies define the
competencies that good simulation engineers should possess.
Incorporating thousands of individual competency statements
across 26 technical areas
Peer-reviewed over several years by NAFEMS technical working
groups and external experts as part of EASIT2 project
These competencies are the foundation for the PSE
Competency Tracker and PSE Certification.

Subsea UK/NSRI – simulation community
• Is a simulation community needed for the UK
subsea sector?
• There is a precedent…
NAFEMS oil and gas focus group
• The NAFEMS CFD working group includes contributors from many industries, several from the oil and gas sector
• The idea of a focus group for oil and gas applications had been mooted for several years. In 2016 we formed a specific oil and gas focus group
• The focus group comprises expert CFD users from across the sector and is currently preparing guidance for CFD practitioners for a range of applications.
NAFEMS oil and gas focus group
• There is already some high-level guidance available (for example, DNV recommended practice guidelines)
• However, there is currently no coordinated system of documentation on how to undertake practical CFD analysis for many oil and gas applications
• Whilst practitioners may agree on the high-level approach, the devil is in the detail, and it is likely that the approaches developed across the industry in the absence of detailed guidance will be inconsistent.
NAFEMS oil and gas focus group
• Experienced CFD engineers are
undoubtedly undertaking similar kinds of
routine simulations but have established their
own methods and workflows which will
differ, so CFD predictions will be inconsistent
across our industry
• For CFD engineers entering the industry there
is no coordinated literature that can assist
when establishing new capability.
NAFEMS oil and gas focus group
• Inconsistency is bad for the industry – it
reduces confidence in advanced simulation
approaches
• Without low-level, detailed guidance aimed
at the practitioner, as the use of CFD and
other simulation methods increases, so will
inconsistency
• Without low-level guidance, there is a
greater risk of poor practice…

Severe expansion in mesh causes unrealistic
distortion of plume envelope
Inappropriate meshing motivated by HPC complacency prevented the CFD mesh from being adequately refined in the regions of interest
Example for atmospheric dispersion
NAFEMS oil and gas focus group
NAFEMS oil and gas focus group
• The focus group has set out to share knowledge and collaborate for the good of the industry
– review existing documentation and guidance
– produce practical guidance for CFD
– identify potential shortcomings in existing CFD software
– blind tests
– verification and validation• It may not be possible to reach consensus on
everything, but at least any open questions can be properly documented and returned to when better V&V data becomes available.

• NAFEMS is not the only organisation to recognise

• TechnipFMC is leading a JIP in Houston aiming to

• There is significant crossover between the JIP
members and the NAFEMS focus group.

Subsea UK/NSRI simulation community

UK focussed International
CFD, FEA, other simulation methods O&GFG has so far focussed on CFD, but NAFEMS remit is all forms of engineering
simulation
Oil and gas, offshore wind, subsea mining, wave/tidal, defence, ocean science
O&GFG is oil and gas in name – many of the guides will be applicable to other
industry sectors
