1 ISO ed2 Overview and Status September, 2013 Keith A. Hunten, P.E. Lockheed Martin Aeronautics Co. Advanced Development Programs

2 AP 209 ed2 Status The first edition of AP209 has been modularized and new capabilities added Built upon the full capabilities of AP203 ed2, now AP242 In addition to the AP209 ed1 classical finite element analysis, a STEP adaptation of CGNS computational fluid dynamics capability has been added that was built upon a new generic mesh based engineering analysis framework A discrete and continuous field representation based upon DT-NURBS capability was integrated with all types of analytical models The 19 new modules have been balloted and approved The AP209 ed2 DIS document is available Currently out for a Draft International Standard (DIS) ballot set to close in October 2013

3 AP 209 ed2 Modular Overview Product Identification Core Activity and Work Management Product Structure Analysis Identification Rules and Requirement Product Concept, Configuration & Effectivity Analysis Model Management Resource Information Product characteristic Fields and Properties Document Management Analysis Shape Geometric Shape Geometric Shape Related Analysis Control and Results AP242 Modules Presentation

4 (AP209) ed2: Multidisciplinary Analysis and Design Analysis Discipline Product Definitions Finite Element Analysis (FEA) Computational Fluid Dynamics (CFD) Generic Structured/ Unstructured Mesh and Mesh-less Numerical Analyses Kinematic Analyses Discrete and Continuous Scalar, Vector and Tensor Fields (properties, loads, results) Analysis Reports AP242-Based Design Discipline Product Definitions Part, product, document identification and management (PLM) Activity/Work Management Product Structure (Assemblies) GD&T/PMI Information Presentation/Draughting 3D/2D Shape Representations AP242 Commonality Advanced B-Representation Faceted B-Representation Manifold Surfaces With Topology Wireframe & Surface without Topology Wireframe Geometry with Topology Tessellated Shape Representation Composite Constituent Shape Representations CFD & Panel Aero CAD FEA Information Associatively Shared Between Analysis & Design Part Definitions 3D Shape Representations Composite Constituents Material Specifications & Properties Composite Constituents Ply Boundaries, Surfaces and Volumes Laminate Stacking Tables Composite Assemblies Reinforcement Orientations Material Specifications & Properties Composites Homogeneous (metallic)

5 CAD to Mesh/CAE Shape Management CAD (DMU) Idealisation/Cleaning to MESH creation and analysis AP 209 ed2 supports the idealised CAD Geometry when the CAD model has been updated/modified AP209 manages both a design and analysis product structure so versioning in each is supported, along with relationships between the analysis and design versions AP209 ed2 can represent a nominal design shape, an idealized analysis shape(s), and analysis shape(s) Part Allows Analysis to Revise Independently of Design Analysis Part Version Assembly Design Discipline Product Definition Analysis Design Version Relationship Analysis Version Analysis Discipline Product Definition Nominal Design Shape Idealized Analysis Shape Analysis Model Shape

7 What are the Links to Other Standards? AP233 (SE), AP239 (PLCS) Only the product structure core modules in AP209 ed2 are common between AP233, AP239 AP242 (Managed Model Based 3D Engineering) All of AP242 is a subset of AP209 ed2 AP237 (Fluid dynamics) The entire contents of AP237 have been subsumed in AP209 ed2

8 Development and Review Involvement The participants in the development of AP209 ed2 over the last 12 years include: MSC.Software, EPM Technologies, LKSoft, eurostep, Theorem, CAESAR Systems Lockheed Martin Aeronautics, Boeing (Commercial, Military, and Computer Systems), Northrop Grumman, BAE Systems, Volvo Aero (EAR model), JPL, NASA, ESA, AIAA/NASA CGNS The EU GEM (Generic Engineering Analysis Model) project Many other members of ISO TC194/SC4/WG3/T9 Engineering Analysis The Composites structure and shape capabilities shared with AP203 ed2 and AP242 have been extensively reviewed, implemented and piloted in the LOTAR program LM Aero, BAE Systems, EADS, Airbus, Boeing Vistagy/FIberSim (in CATIA, Unigraphics, and Pro/E) and Dassault Systemes CATIA are implementing it
