Relationship between NAFEMS and ISO
Longstanding history of collaboration with ISO -
NAFEMS CAD/FE working group was formed at about
the time work began on STEP (ISO 10303) - mid
1980s - NAFEMS has liaison status with ISO
TC184/SC4 - NAFEMS made significant
contributions to ISO 10303-104 "Finite element
analysis", which is the key part of AP 209
edition 1 - NAFEMS managed the GEM (Generic
Engineering analysis Model) project which
proposed extensions to AP 209, and produced
initial inputs to - ISO 10303-51
Mathematical Description - ISO 10303-52
Mesh - ISO 10303-53 Numerical analysis
These parts are now used within AP 209 edition 2
which brings together structural analysis and
CFD.

What is Simulation Data Management (SDM)?

• Systematic management of documents, data, and
  processes associated with modeling, simulation
  and analysis
• Provides for the management of data objects and
  metadata at all levels of granularity and
  abstraction, including design and analysis
  parameters, requirements, and results.
• Used for work-in-progress and completed data,
  collaboration, knowledge capture, reuse, and
  long-term archival
• Support execution of analysis processes (may
  include process authoring)
• Roots started in the 1980s with need for common
  denominator across applications

State of SDM Issues

• Still a relatively new discipline with lessons to
  be learned1
• Engineers may view product data management (PDM)
  systems as difficult to use
• Simulation has unique requirements and issues as
  compared to PDM
• Number and size of files
• Much of analysis is abstract and not associated
  with product parts
• Interchangeable standards (or lack) between
  vendor software, storage analysis results
• COTS software purposed for managing simulation
  data has only recently become available, and is
  still undergoing significant maturation
  integration of simulation software and data
  management is increasing
• Interest in simulation data management has
  greatly increased in the past several years
• For most engineers, formal data management is
  not part of a daily
  routine.

Origin of the Simulation Data Management Working
Group NAFEMS 2007Work Session on the Management
of Simulation Data
Take Control of Your Analysis and Simulation
Data

• Well-attended work session on SDM in Sept 2007
  (Troy, MI USA)
• Over 33 companies, including software vendors,
  and 110 attendees
• Attendees confirmed interest general need for
  more communication on SDM
• NAFEMS formally created the SDMWG in June 2008

Mission

• The mission of the NAFEMS Simulation Data
  Management Working Group (SDMWG) is to provide a
  vendor-neutral, end-user driven consortium that
  promotes the advancement of the technology and
  practices associated with the management of
  engineering simulation data and processes. This
  includes education, communication, promotion of
  standards, and development of requirements that
  will have general benefits to the simulation and
  analysis community with the identification of
  benchmarks and major strategic issues (grand
  challenges).

15
Vision

• The SDMWG vision is that SDM is to be
  cost-effective, easy to use, and ubiquitous. SDM
  is integrated with the business, engineering
  modeling and simulation processes, used for
  work-in-progress and completed data,
  collaboration, knowledge capture, reuse, and
  long-term archival. Data management methods are
  integrated with simulation analysis methods,
  ranging from closed-form to highly complex
  multiphysics numerical models.
• Engineering simulation data encompasses the data,
  models, processes, documents and metadata
  intrinsic to performing modeling, simulation, and
  analysis. SDM provides for the management of data
  objects and metadata at all levels of granularity
  and abstraction, including design and analysis
  parameters, requirements, and results. SDM
  solutions are integrated with other systems and
  databases that manage engineering and product
  data.
• SDM systems are available for managing and
  executing a wide range of modeling and simulation
  data and processes, across the breadth of
  engineering disciplines, supporting a
  heterogeneous analysis environment. Integration
  of design, test, and manufacturing data with
  modeling, simulation and analysis is supported.

NAFEMS Simulation Data Management Survey

• Assess community awareness, interest, and
  requirements for SDM
• Results will help set priorities and direction of
  the SDMWG

Relationship between NAFEMS and ISO for
Simulation Data Management Future

• NAFEMS/ISO collaboration activities for SDM still
  to be determined
• Has been suggested
• The use of the Semantic Web for engineering
  analysis requires ontologies of analysis types,
  model types, loading types, boundary condition
  types, etc. These ontologies could be maintained
  by NAFEMS acting as an ISO Maintenance Agency.
• The digital curation of analysis data, some of
  which is inevitably in native file formats,
  requires a registry of native file formats and
  software versions able to read them. The
  management of such a registry is not within the
  scope of ISO but is complementary to the work of
  ISO. This registry could be maintained by NAFEMS
• Survey may identify other ideas for collaboration
